Q: When Harriett vacuumed the sofa and chair she found 10 quarters, 3 dimes, 3 nickels, and 5 pennies. How much money did Harriett find?
A: She found 10 quarters that are $0.25 each so she found 10 * .25 = $2.50. She found 3 dimes that are $0.10 each so she found 3 * .10 = $0.30. She found 3 nickels that are $0.05 each so she found 3 * .05 = $0.15. She found 5 pennies that are $0.01 each so she found 5 * .01 = $0.05. All total she found 2.50 + .30 + .15 + .05 = $3.00 in change. The answer is 3.
Question: Joy is winding balls of yarn for her cat to play with. The first ball is half the size of the second ball. The third ball is three times as large as the first ball. She used 27 feet of yarn for the third ball. How many feet of yarn did she use for the second ball?
Answer: The first ball is a third of the size of the third ball, so it used 27 / 3 = 9 feet of yarn. The second ball is twice the size of the first ball, so she used 9 * 2 = 18 feet of yarn. The answer is 18.
[Question]It is Roger’s turn to provide a snack for the baseball team after the game and he has decided to bring trail mix. The trail mix comes in packs of 6 individual pouches. Roger has 13 members on his baseball team, plus 3 coaches and 2 helpers. How many packs of trail mix does he need to buy?
[Answer]Roger will need 13 + 3 + 2 = 18 pouches of trail mix. If you divide the amount of trail mix pouches by the amount in each pack, 18 / 6 = 3 packs of trail mix. The answer is 3.
Q: To make a cherry pie, Veronica needs 3 pounds of pitted cherries. There are 80 single cherries in one pound of cherries.  It takes 10 minutes to pit 20 cherries. How many hours will it take Veronica to pit all the cherries?
A: There are 80 cherries in a pound and she needs 3 pounds to make a pie so she needs 80 * 3 = 240 cherries. It takes her 10 minutes to pit a unit of 20 cherries. She has 240 / 20 = 12 units of cherries to pit. It takes 10 minutes to pit a unit of cherries and she has 12 units so it will take her 10 * 12 = 120 minutes. 60 minutes are in 1 hour and it takes her 120 minutes so that’s 120 / 60 = 2 hours. The answer is 2.
Question: Mary and Ann are going sledding. Mary slides down a hill that's 630 feet long at a speed of 90 feet/minute. Ann slides down a hill that's 800 feet long at a rate of 40 feet/minute. How much longer does Ann's trip take than Mary?
Answer: First find the total time Mary's trip takes: 630 feet / 90 feet / minute = 7 minutes. Then find the total time Ann's trip takes: 800 feet / 40 feet / minute = 20 minutes. Then subtract Mary's time from Ann's time to find the difference: 20 minutes - 7 minutes = 13 minutes. The answer is 13.

They spent $8 each on cheeseburgers and milkshakes because 3 + 5 = 8. They spent $16 on these items in total because 2 x 8 = 16. They spent $24 on their meal because 16 + 8 = 24. They had $30 to start because 24 / .8 = 30. His cousin had $10 because 30 - 20 = 10. The answer is 10.
