Q: A pickup truck can fill 20 eight gallon water cans (each can filled three quarters of its capacity) in three hours. If each can is filled to full capacity instead, how long, in hours, will it take to fill 25 cans?
A: Each can is filled with 8 / 4 * 3 = 6 gallons of water. A total of 6 * 20 = 120 gallons of water is filled in 3 hours. In 1 hour, 120 / 3 = 40 gallons of water is filled. 25 full cans can hold 25 * 8 = 200 gallons of water. It will take 200 / 40 = 5 hours to fill 25 cans to full capacity. The answer is 5.
Question: A mad scientist created a shrink ray device that, when used on anything, would cause it to shrink by 50%. The scientist, eager to use his new invention, looked through his house for something to shrink zap. The first thing he found and zapped was his wife, who at the time was carrying a tray containing 5 cups filled with coffee. If each coffee cup held 8 ounces of fluid before being zapped, how many ounces of coffee remained after his wife and the cups filled with coffee were shrink zapped?
Answer: Before the zap, the wife held 5 cups, each with 8 ounces of coffee, for a total of 5 * 8 = 40 ounces of coffee. After the zap, the coffee cups and their contents were shrunk by 50%, for a total of 0.5 * 40 = 20 ounces of coffee. The answer is 20.
[Question]Luke pays a school fee. His mother gave him one $50 bill, two $20 bills, and three $10 bills. His father gave him four $50 bills, one $20 bill, and one $10 bill. If his parents gave him the exact amount for the school fee, how much is the school fee?
[Answer]Luke's parents gave him 1 + 4 = 5 $50 bills. These $50 bills amount to $50 x 5 = $250. His parents gave him 2 + 1 = 3 $20 bills. These $20 bills amount to $20 x 3 = $60. His parents gave him 3 + 1 = 4 $10 bills. These $10 bills amount to $10 x 4 = $40. Therefore, Luke's school fee is $250 + $60 + $40 = $350. The answer is 350.
Q: To buy a book, you pay $20 for each of the first 5 books at the supermarket, and for each additional book you buy over $20, you receive a discount of $2. If Beatrice bought 20 books, how much did she pay at the supermarket?
A: For the first five books, the total cost is $20 * 5 = $100. For every additional book over $5, you pay $2 less, totaling to $20 - $2 = $18. Beatrice bought 20 books, so the number of books at which she received the $2 discount is 20 - 5 = 15 books. For the 15 books, Beatrice paid 15 * $18 = $270. In total, Beatrice paid $100 + $270 = $370 for the 20 books. The answer is 370.
Question: There were 133 people at a camp. There were 33 more boys than girls. How many girls were at the camp?
Answer: If there were 33 fewer boys at camp, there would be the same number of both boys and girls or 133 - 33 = 100 people. That means that there were 100 / 2 = 50 girls at the camp. The answer is 50.

Quinn catches twice the amount as Alster, who caught 2 frogs so Quinn caught 2 * 2 = 4 frogs. Bret catches three times the amount as Quinn who caught 4 frogs so Bret caught 3 * 4 = 12 frogs. The answer is 12.
