[Question]Susie's pet lizard Moe takes 10 seconds to eat 40 pieces of cuttlebone each day. How long would it take Moe to eat 800 pieces?
[Answer]If it takes Moe 10 seconds to eat 40 cuttlebones, then in one second she eats 40 cuttlebones / 10 seconds = 4 cuttlebones / second. Since the cat eats 4 pieces of cuttlebone in 1 second, 800 pieces will be 800 cuttlebones / 4 cuttlebones / second = 200 seconds. The answer is 200.

[Question]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?
[Answer]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.
Q: Ben has four boxes with ten basketball cards in each box. His mother gave him five boxes with eight baseball cards. If he gives 58 cards to his classmates, how many cards does he has left?
A: Ben has 4 x 10 = 40 basketball cards. His mother gave him 5 x 8 = 40 baseball cards. Thus, Ben has 40 + 40 = 80 cards in all. Therefore, Ben has 80 - 58 = 22 cards left. The answer is 22.
Question: Samantha sleeps an average of 8 hours a night. Her baby sister sleeps 2.5 times as much as Samantha does. Because her father is so tired from watching the baby, for every hour the baby sleeps, he sleeps 30 minutes. How many hours does her father sleep in a week?
Answer:
The baby sleeps 20 hours a day because 2.5 x 8 = 20. The baby sleeps 2 times as much as the father because 60 / 30 = 2. The father sleeps 10 hours a night because 20 / 2 = 10. The father sleeps for 70 hours a week because 7 x 10 = 70. The answer is 70.
