Q: Tony has a bucket that holds 2 pounds of sand. He has a sandbox out back that is two feet deep, four feet wide, and 5 feet long. A cubic foot of sand weighs 3 pounds. Because it's hot outside, he wants to make sure he stays hydrated, so every 4 trips he takes he drinks 3 ounces of bottled water. A 15 ounce bottle of water costs $2. He has $10 with him. How much change will he have after he buys all the water he needs?
A: The sandbox is 40 cubic feet because 2 x 4 x 5 = 40. He needs 120 pounds of sand because 40 x 3 = 120. He will take 60 trips because 120 / 2 = 60. He will need to drink water 15 times because 60 / 4 = 15. He will drink 45 ounces of water because 15 x 3 = 45. He will need 3 bottles of water because 45 / 15 = 3. He will spend $6 on water because 3 x 2 = 6. He will have $4 in change because 10 - 6 = 4. The answer is 4.
Question: Tom uses 10 weight plates each weighing 30 pounds on an exercise machine. This exercise machine uses special technology to make the weights 20% heavier on the lowering portion. How heavy did the weights feel when being lowered?
Answer: The weight stack weighed 10 * 30 = 300 pounds. So the added weight made it 300 * .2 = 60 pounds heavier. So when he lowered the weight it was 300 + 60 = 360 pounds. The answer is 360.
[Question]Two-thirds of all the animals on my street are cats and the rest are dogs. If there are 300 animals on the street, what's the total number of legs of dogs that are on the street?
[Answer]The number of cats on the street is 2 / 3 * 300 = 200. If there are 300 animals on the street, and 200 are cats, there are 300 - 200 = 100 dogs. Since a dog has four legs, the total number of legs the 100 dogs have is 100 * 4 = 400 legs. The answer is 400.
Q: Allison, a YouTuber, uploads 10 one-hour videos of food reviews each day to her channel. She uploaded videos halfway through June, at that pace, and then doubled the number of video hours she uploaded on the remaining days. What's the total number of video hours she has uploaded at the end of the month?
A: Since June has 30 days, halfway is 1 / 2 * 30 = 15. The total number of video hours halfway through June is 10 * 15 = 150. When she doubled the number of video hours, the total per day became 10 * 2 = 20. The total number of video hours for the remaining days is 15 * 20 = 300. The total number of video hours for the whole month is 300 + 150 = 450. The answer is 450.
Question: One set of barrettes costs $3 each, and one comb costs $1 each. Kristine buys one set of barrettes and one comb. Crystal buys three sets of barrettes and one comb. How much do the two girls spend altogether?
Answer: Kristine spends $3 + $1 = $4. Three sets of barrettes cost 3 x $3 = $9. Crystal spends $9 + $1 = $10. Therefore, the two girls spend $4 + $10 = $14. The answer is 14.
Q: Bruce buys 5 packs of crayons at $5 each, 10 books at $5 each, and 3 calculators at $5 each. If he has $200, how many bags can he buy with the change if one costs $10 each?
A:
He pays 5 * 5 = $25 for buying crayons. He pays 10 * 5 = $50 for buying books. He pays 3 * 5 = $15 for buying calculators. The change he has for buying bags is 200 - 25 - 50 - 15 = $110. The number of bags he can buy is 110 / 10 = 11 bags. The answer is 11.
