Q: Yanni has 5 paintings that combined, take up 200 square feet. 3 of the paintings are 5 feet by 5 feet. 1 painting is 10 feet by 8 feet. If the final painting is 5 feet tall, how wide is it?
A: Each 5 by 5 painting is 25 square feet because 5 x 5 = 25. All three of them take up 75 square feet because 3 x 25 = 75. The 10 by 8 painting takes up 80 square feet because 10 x 8 = 80. These four paintings take up 155 square feet because 80 + 75 = 155. The final painting is 45 square feet because 200 - 155 = 45. If it is 5 feet wide it is 9 feet tall because 45 / 5 = 9. The answer is 9.

[Question]Ray buys a pack of hamburger meat for $5.00, a box of crackers for $3.50, 4 bags of frozen vegetables at $2.00 per bag and a pack of cheese for $3.50 at the grocery store. Because he is a store rewards member, he gets 10% off of his purchase. What does his total grocery bill come to?
[Answer]He buys 4 bags of frozen vegetables for $2.00 a bag so that’s 4 * 2 = $8.00. The meat is $5.00, the crackers are $3.50, the vegetables are $8.00 and the cheese is $3.50 for a total of 5 + 3.50 + 8 + 3.50 = $20.00. He gets 10% discount on his $20.00 purchase so that’s .10 * 20 = $2.00 off. His final grocery bill will be 20 - 2 = $18.00. The answer is 18.
Q: Sasha heard that planting trees helps to reduce the local temperature. For each tree planted, the temperature drops .1 degree. A tree costs $6 to plant. If she got the local temperature to drop from 80 to 78.2, how much did it cost to plant the trees?
A: The temperature dropped 1.8 degrees because 80 - 78.2 = 1.8. She planted 18 trees because 1.8 / .1 = 18. It cost $108 to plant the trees because 18 x 6 = 108. The answer is 108.
Question: Clayton plays basketball on a team. He has played three games so far. In the first game, he scored 10 points. In the second game, he scored 14 points. In the third game, he scored 6 points.
