[Question]It costs $.10 to print one page. Jenny wants to print 7 copies of her 25-page essay. She also wants to buy 7 pens that each cost $1.50. If she pays the store with 2 twenty dollar bills, how much money should she get in change?
[Answer]Jenny needs to print 7 * 25 = 175 pages. This will cost 175 * $.10 = $17.5. The pens will cost 7 * $1.50 = $10.50. In total, she will spend $17.5 + $10.5 = $28. Since she pays with 2 twenty dollar bills she pays with 2 * 20 = 40 dollars. Thus, she will get $40 - $28 = $12 in change. The answer is 12.
Q: I went to the music shop and there were CDs of The Life Journey for $100, A Day a Life for $50, and When You Rescind for $85 on display. If I bought 3 of each CD to share with my friends, what's the total amount of money I spent in the shop?
A: The total cost of The Life Journey is 3 × $100 = $300. The total cost of When You Rescind is 3 × $85 = $255. The total cost of A Day a Life is 3 × $50 = $150. The total cost for all the CDs is $150 + $255 + $300 = $705. The answer is 705.

[Question]Ann is cutting fabric to make curtains. She cuts a 4 foot by 6 foot rectangle for the living room, and a 2 foot by 4 foot rectangle for the bedroom. If the bolt of fabric is 16 feet by 12 feet, how much fabric is left in square feet?
[Answer]First figure out how many square feet the original bolt of fabric was: 16 feet * 12 feet = 192 square feet. Then figure out how much fabric Ann took for the living room curtains: 4 feet * 6 feet = 24 square feet. Then figure out how much fabric Ann took for the bathroom curtains: 2 feet * 4 feet = 8 square feet. Finally, subtract the square footage of both sets of curtains from the total square footage: 192 - 24 - 8 = 160 square feet. The answer is 160.
[Question]Tobias is buying a new pair of shoes that costs $95. He has been saving up his money each month for the past three months. He gets a $5 allowance a month. He also mows lawns and shovels driveways. He charges $15 to mow a lawn and $7 to shovel. After buying the shoes, he has $15 in change. If he mows 4 lawns, how many driveways did he shovel?
[Answer]
He saved up $110 total because 95 + 15 = 110. He saved $15 from his allowance because 3 x 5 = 15. He earned $60 mowing lawns because 4 x 15 = 60. He earned $35 shoveling driveways because 110 - 60 - 15 = 35. He shoveled 5 driveways because 35 / 7 = 5. The answer is 5.
