Q: Three companies, A, B, and C, each purchased 10 ad spaces on a newspaper, with each ad space having a size of 12 foot by 5-foot rectangle. If each square foot ad was charged at $60, how much money did the three pay for the ads combined?
A: A size 12 foot by 5 - foot rectangle ad takes 12 * 5 = 60 square feet since the area of a rectangle is l * w. If each company bought 10 ad spaces, the total area that their ads took is 60 * 10 = 600 square feet. If each square foot of ad space was charged at $60, 600 square feet of ads cost $60 * 600 = $36000. If all three companies each purchased an equal number of ad space, together they paid $36000 * 3 = $108000. The answer is 108000.

Q: Cynthia harvested 67 potatoes from her garden. After washing them, she cut 13 of them into wedges. She then halved the remaining potatoes and made french fries with one half, and potato chips with the other half. If one potato can be cut into 8 wedges or make 20 potato chips, how many more potato chips than wedges did Cynthia make?
A: Cynthia was left with 67 - 13 = 54 potatoes after making wedges. She used 54 / 2 = 27 potatoes to make potato chips. Cynthia made 13 x 8 = 104 wedges. She made 27 x 20 = 540 potato chips. Cynthia made 540 - 104 = 436 more potato chips than wedges. The answer is 436.

Q: Bonnie and Samuel went to the market together. Bonnie bought 8 apples. Samuel bought 20 more apples than Bonnie. Samuel then ate half of them and used 1/7 of them to make apple pie. How many apples does Samuel have left?
A:
Samuel bought 20 + 8 = 28 apples. Samuel ate 28 / 2 = 14 apples. Samuel used 28 / 7 = 4 to make apple pie. Samuel has 28 - 14 - 4 = 10 apples left. The answer is 10.
