[User] Tony has a terrible toothache and decides to buy some painkillers from the store.  He picks up a bottle of 50 pills and takes them home.  He takes 2 pills each day three times a day for the first 2 days, before cutting this amount in half for the next 3 days.  On the sixth day, he takes a final 2 pills in the morning and ends up feeling better.  How many pills are left in the bottle?

[Assistant]
<think>
Tony starts with 50 pills and takes 2 pills each 3 times a day, meaning he takes 2*3=6 pills in total.
Tony repeats this process for two days in total, meaning over those two days he takes 2*6= <<2*6=12>>12 pills
Tony then cuts down his pill usage in half, meaning he's now taking 6/2= <<6/2=3>>3 pills a day.
Since he repeats this process for three days, that means he takes 3*3= <<3*3=9>>9 pills for that period.
Adding in the two pills Tony took on the final day, that means he took 12+9+2=<<12+9+2=23>>23 pills.
Since there were 50 pills in the bottle to begin with, this means Tony has 50-23=<<50-23=27>>27 pills remaining.

[User] One pie costs $4 for a piece. Each pie is having 3 pieces. During one hour the bakery can make 12 pies. Creating one pie costs the bakery $0.5. Considering the bakery would be able to sell all pie pieces, how much money would it make?

[Assistant]
<think>
If the bakery can make 12 pies, this means there would be 12 * 3 = <<12*3=36>>36 pie pieces.
For all the pieces the bakery would make 36 * 4 = $<<36*4=144>>144.
The cost of making 12 pies is 12 * 0.5 = $<<12*0.5=6>>6.
That means the bakery would make 144 - 6 = $<<144-6=138>>138.

[User] A rectangular plot of private property is fenced in by a chain-link fence. The long sides of the plot are three times the length of the short sides. One short side of the fence is rusted from being hit by a sprinkler and needs to be replaced. If all the sides of the fence together are 640 feet long, how many feet of fence need to be replaced?

[Assistant]
<think>
Let S be the length of the short side of the fence.
Thus, the length of a long side of the fence is 3S.
There are 2 of each side, so the whole fence is 2S + 2 * 3S = 2S + 6S = 8S long.
The whole fence is 8S = 640 feet long.
Thus, the short side of the fence that needs to be replaced is S = 640 / 8 = <<640/8=80>>80 feet long.

[User] Nate got lost looking for his car in the airport parking lot. He had to walk through every row in Section G and Section H to find it. Section G has 15 rows that each hold 10 cars. Section H has 20 rows that each hold 9 cars. If Nate can walk past 11 cars per minute, how many minutes did he spend searching the parking lot?

[Assistant]
<think>
First find the number of cars in Section G by multiplying the number of rows by the number of cars per row: 15 rows * 10 cars/row = <<15*10=150>>150 cars
Then do the same thing for Section H: 20 rows * 9 cars/row = <<20*9=180>>180 cars
Then add the two quantities of cars to find the total number of cars Nate walked past: 150 cars + 180 cars = <<150+180=330>>330 cars
Finally, divide the number of cars Nate passed by the numbers he passes each minute to find how long he spent searching: 330 cars / 11 cars/minute = <<330/11=30>>30 minutes

[User] On a road map, 1/4 inch represents 8 miles of actual road distance. The towns of Pence and Hillcrest are represented by points 3 3/8 inches apart on the map. What is the actual distance, in miles, between the towns?

[Assistant]
<think>
If 1/4 inch on the map represents 8 miles on real land, 1 inch represents 4 * 8 = 32 miles.
Since 1 inch represents 32 miles, 3 inches represent 3 * 32 = <<3*32=96>>96 miles.
1/ 4 inch represents 8 miles, 1/8 inch represents 8 / 2 = <<8/2=4>>4 miles because 1/8 is half of 1/4.
If 1/8 inch represents 4 miles, 3/8 of an inch represents 3 * 4 = 12 miles.
This means 3 3/8 inches on the map translate to 96 + 12 = 108 miles.

[User] Adam goes to a small school, which teaches 80 students in three classes. 40% of the students are in class A, and class B has 21 students fewer than class A. The rest are in class C. How many students are in this class?

[Assistant]
<think>
In class A, there are 40/100 * 80 = <<40/100*80=32>>32 students.
In class B, the number of students is less by 21, which means class B has 32 - 21 = <<32-21=11>>11 students.
That means 80 - 32 - 11 = <<80-32-11=37>>37 students are in class C.

[User] Every hour past noon shadows from a building stretch an extra 5 feet, starting at zero at noon.  How long are the shadows from the building 6 hours past noon in inches?

[Assistant]
<think>
If the shadows lengthen by 5 feet per hour, this means that in 6 hours the shadows would have lengthened from zero to 5*6=<<5*6=30>>30 feet.
Since there are 12 inches in every foot, this means the building's shadow would be 30*12= <<30*12=360>>360 inches in length.

[User] You can buy 4 apples or 1 watermelon for the same price. You bought 36 fruits evenly split between oranges, apples and watermelons, and the price of 1 orange is $0.50. How much does 1 apple cost if your total bill was $66?

[Assistant]
<think>
If 36 fruits were evenly split between 3 types of fruits, then I bought 36/3 = <<36/3=12>>12 units of each fruit
If 1 orange costs $0.50 then 12 oranges will cost $0.50 * 12 = $<<0.5*12=6>>6
If my total bill was $66 and I spent $6 on oranges then I spent $66 - $6 = $<<66-6=60>>60 on the other 2 fruit types.
Assuming the price of watermelon is W, and knowing that you can buy 4 apples for the same price and that the price of one apple is A, then 1W=4A
If we know we bought 12 watermelons and 12 apples for $60, then we know that $60 = 12W + 12A
Knowing that 1W=4A, then we can convert the above to $60 = 12(4A) + 12A
$60 = 48A + 12A
$60 = <<60=60>>60A
Then we know the price of one apple (A) is $60/60= $<<60/60=1>>1

[User] Jill and her brother Jack are going apple picking.  Jill's basket can hold twice as much as Jack's basket when both are full.  Jack's basket is full when it has 12 apples, but currently space for 4 more.  How many times could Jack's current number of apples fit into Jill's basket?

[Assistant]
<think>
Since Jill's basket can hold twice as much as Jack's, and Jack's is capable of holding 12 apples in total, this means Jill's basket can hold 12*2=<<12*2=24>>24 apples in total.
Since Jack has 4 less than the maximum amount of apples he can fit in his basket, this means Jack has 12-4= <<12-4=8>>8 apples in his basket.
Therefore, Jill's basket can hold 24/8= <<24/8=3>>3 times the amount of apples Jack is currently carrying.

[User] An Italian restaurant earns $600 every weekday and twice as much on the weekend. How much money does it earn by the end of the month?

[Assistant]
<think>
On weekdays it earns $600/weekday * 5 weekdays = $<<600*5=3000>>3000
During the weekend it earns twice as much each day so it makes ($600 * 2)/weekend day * 2 weekend days = $<<(600*2)*2=2400>>2400
Every week it earns $3000 + $2400 = $<<3000+2400=5400>>5400
By the end of the month, it earns $5400/week * 4 weeks = $21600

[User] Jimmy is going to sell pizzas at the carnival to make some money. The carnival only gave him 7 hours to do so. He bought a 22kg sack of flour to make his pizzas and he takes 10 min to make each pizza for the customers. At the end of the 7 hours, he saw some flour was left. Knowing that each pizza needs 0.5kg of flour to make, how many pizzas can he make to bring home with the flour left?

[Assistant]
<think>
Each hour Jimmy makes 60min ÷ 10min/pizza = <<60/10=6>>6 Pizzas
The number of total pizzas made equals 7 hours x 6 pizzas/hour = <<7*6=42>>42 pizzas

[User] Ayla has a customer care job whose primary role is to hear complaints from customers and advise them on the best way to solve their problems. She talks with each customer for a limited amount of time, and each phone call is charged five cents per minute. If each call lasts 1 hour, what's the phone bill at the end of the month if she manages to talk to 50 customers a week?

[Assistant]
<think>
An hour has 60 minutes.
If each call lasts an hour, the total amount of money charged is 60*.05 = $<<60*.05=3>>3 for 1 customer.
When she talks to 50 clients in a week, the total amount of money charged is 50*3 = $<<50*3=150>>150.
In a month of 4 weeks, the phone bill is 150*4 = $<<150*4=600>>600.

[User] Oliver has 10 $20 and 3 $5 bills. William has 15 $10 and 4 $5 bills. How much more money does Oliver have than William?

[Assistant]
<think>
Oliver's $20 bills amount to $20 x 10 = $<<20*10=200>>200.
Oliver's $5 bills amount to $5 x 3 = $<<5*3=15>>15.
So, Oliver has a total of $200 + $15 = $<<200+15=215>>215.
William's $10 bills amount to $10 x 15 = $<<10*15=150>>150.
William's $5 bills amount to $5 x 4 = $<<5*4=20>>20.
So, William has a total of $150 + $20 = $<<150+20=170>>170.
Therefore, Oliver has $215 - $170 = $<<215-170=45>>45 more than William.

[User] Hansel makes $30,000 a year and just received a 10% raise.  Gretel makes the same amount as Hansel but received a 15% raise.  How much more money will Gretel make compared to Hansel?

[Assistant]
<think>
Hansel makes $30,000 and received a 10% raise so his raise is 30,000*.10 = $3,000.00
Hansel now makes 30,000+ 3,000 = $<<30000+3000=33000>>33,000 a year
Gretel makes $30,000 and received a 15% raise so her raise is 30,000*.15 = $4,500.00
Gretel now makes 30,000+4,500 = $<<30000+4500=34500>>34,500 a year
If Gretel makes $34,500 a year and Hansel makes $33,000 then Gretel makes 34,500-33,000 = $<<34500-33000=1500>>1,500 more a year than Hansel

[User] Sabrina went to the library and found a historical series novel called The Rangers Apprentice. There are 14 books in the series, and each book has 200 pages. She read four books in a month and half the number of books remaining in the second month. What's the total number of pages Sabrina has to read to finish the whole series?

[Assistant]
<think>
The total number of pages in the series is 14 books * 200 pages/book = <<14*200=2800>>2800 pages.
Sabrina read 4 books *200 pages/book = <<4*200=800>>800 pages in the first month.
She still has 14 books - 4 books = <<14-4=10>>10 books after reading four books.
In the second month, she read 1/2*10 books = <<1/2*10=5>>5 books.
The total number of pages she read is 5 books * 200 pages/book = <<5*200=1000>>1000 in the second month.
In total, Sabrina 1000 pages + 800 pages = <<1000+800=1800>>1800 pages in two months.
Sabrina has to read 2800 pages - 1800 pages = <<2800-1800=1000>>1000 more pages to complete the total series.

[User] Lily has 5 lottery tickets to sell.  She sells the first ticket for $1.  She then sells each successive ticket for a dollar more than the previous ticket. She plans to keep a $4 profit and give the remaining money as the prize. How much money will the winner of the lottery receive?

[Assistant]
<think>
The second ticket sold will cost $1 + $1 = $<<1+1=2>>2.
The third ticket sold will cost $2 + $1 = $<<2+1=3>>3.
The fourth ticket sold will cost $3 + $1 = $<<3+1=4>>4.
The fifth ticket sold will cost $4 + $1 = $<<4+1=5>>5.
The total money collected is $1 + $2 + $3 + $4 + $5 = $<<1+2+3+4+5=15>>15.
After taking profit, the total prize money will be $15 - $4 = $<<15-4=11>>11.

[User] Matt buys a massager.  At the lowest setting, it vibrates at 1600 vibrations per second.  At the highest setting, it vibrates 60% faster.  Matt uses it for 5 minutes at the highest setting.  How many vibrations does he experience?

[Assistant]
<think>
At the highest setting, it vibrates 1600*.6=<<1600*.6=960>>960 vibrations per second faster than the lowest setting
So it vibrates at 1600+960=<<1600+960=2560>>2560 vibrations per second
Matt uses it for 5 minutes so that is 5*60=<<5*60=300>>300 seconds
That means he experienced 2560*300=<<2560*300=768000>>768,000 vibrations

[User] Bran's tuition fee is $90. He does a part-time job that pays him $15 per month and he has a scholarship that takes care of 30% of his tuition fee. If he needs to pay his tuition fee within 3 months, how much does Bran still need to pay?

[Assistant]
<think>
Bran's scholarship pays $90 x 0.30 = $<<90*0.30=27>>27 to his tuition fee.
So, the total amount he still needs to pay is $90 - $27 = $<<90-27=63>>63.
And Bran will be able to earn $15 x 3 = $<<15*3=45>>45 after working for 3 months.
Therefore, the total amount he still needs to pay is $63 - $45 = $<<63-45=18>>18.

[User] John decides to get gym memberships so he can get in shape.  The gym close to his house is close but doesn't have everything he wants so he gets two different gym memberships.  The cheap one costs $10 a month and has a sign-up fee of $50.  The second gym is 3 times more expensive and it has a sign-up fee of 4 months membership.  How much total did he pay in the first year for gym membership?

[Assistant]
<think>
The cheap gym cost 10*12=$<<10*12=120>>120 for monthly fees
So the total cost was 120+50=$<<120+50=170>>170
The more expensive gym cost 3*10=$<<3*10=30>>30 per month
That means the sign-up fee was 30*4=$<<30*4=120>>120
The monthly fees for the expensive gym comes out to 30*12=$<<30*12=360>>360 per year
So the total cost for the expensive gym was 360+120=$<<360+120=480>>480
So his total cost was 480+170=$<<480+170=650>>650
