[Question]: Mary is building a mosaic for her school cafeteria's wall. It will be 10 feet tall and 15 feet long. Each tile she uses is 1 inch square. How many tiles will she need?
[Answer]: First convert the length of the mural to inches: 15 feet * 12 inches / foot = 180 inches. Then convert the height of the mural to inches: 10 feet * 12 inches / foot = 120 inches. Then multiply the length and the height to find the total area of the mural: 180 inches * 120 inches = 21600 square inches. Since each tile is 1 square inch, this is also the number of tiles she needs.
So the answer is 21600.

[Question]: Jake sold 10 more stuffed animals than Thor. Quincy sold ten times as many stuffed animals as Thor. If Quincy sold 200 stuffed animals, how many more stuffed animals did Quincy sell than Jake?
[Answer]: Thor sold 200 / 10 = 20 stuffed animals. Jake sold 20 + 10 = 30 stuffed animals. Quincy sold 200 - 30 = 170 more stuffed animals than Jake.
So the answer is 170.

[Question]: Joel is picking peppers from his garden. He picks 7 on Sunday, 12 on Monday, 14 on Tuesday, 12 on Wednesday, 5 on Thursday, 18 on Friday and 12 on Saturday. He knows that in his garden 20% of the peppers are hot and the rest are not. How many non-hot peppers did he pick?
[Answer]:
He picked 80 peppers because 7 + 12 + 14 + 12 + 5 + 18 + 12 = 80. 80% of the peppers are not hot because 100 - 20 = 80. He picked 64 non - hot peppers because 80 x .8 = 64.
So the answer is 64.
