Question: Jack goes up three flights of stairs, then down six flights of stairs. If each flight of stairs has 12 steps that each each 8 inches high, how many feet further down is Jack than when he started?
Answer: First find the number of inches in each flight of stairs: 12 steps * 8 inches / step = 96 inches. Then find the net number of flights of stairs Jack went down: 6 flights - 3 flights = 3 flights. Then multiply than number by the number of inches per flight to find how many inches further down he is: 96 inches / flight * 3 flights = 288 inches. Then divide that number by 12 to find the number of feet down he is: 288 inches / 12 inches / foot = 24 feet. The answer is 24.
[Question]Josh went to the shopping center. He bought 9 films and 4 books. He also bought 6 CDs. Each film cost $5, each book cost $4 and each CD cost $3. How much did Josh spend in all?
[Answer]The cost of the films is 9 × $5 = $45. The cost of the books is 4 × $4 = $16. The cost of the CDs is 6 × $3 = $18. Josh spent $45 + $16 + $18 = $79 in total. The answer is 79.
Q: Aubrey is planting tomatoes and cucumbers in her garden. For each row of tomato plants, she is planting 2 rows of cucumbers. She has enough room for 15 rows of plants in total. There is enough space for 8 tomato plants in each row. If each plant produces 3 tomatoes, how many tomatoes will she have in total?
A: Since one out of every 3 rows will contain tomato plants, there will be 15 / 3 = 5 rows of tomato plants. This gives her enough room to plant 5 rows * 8 plants / row = 40 tomato plants. The plants will produce a total of 40 * 3 = 120 tomatoes. The answer is 120.
Question: Josh built his little brother a rectangular sandbox. The perimeter of the sandbox is 30 feet and the length is twice the width. What is the width of the sandbox?
Answer: There are four sides to a rectangle, the width is W and so the length is 2W, and we can put that in this equation: W + W + 2W + 2W = 30 feet. If we add the sides together, we get 6W = 30 feet. To find W, we divide both sides by 6, like this: 6W / 6 = 30 feet / 6, so W = 5 feet. The answer is 5.

Since a dozen has 12 items, a half dozen has 1 / 2 * 12 = 6 items. Since Jamal bought four half dozen colored crayons, he bought 4 * 6 = 24 colored crayons. If each crayon's cost was $2, Jamal paid $2 * 24 = $48 for all the crayons he bought. The answer is 48.
