Q: Each purple book has 230 pages. Each orange book contains 510 pages. Mirella read 5 purple books and 4 orange books. How many more orange pages did she read than purple pages?
A: Purple = 5 * 230 = 1150 pages. Orange = 4 * 510 = 2040 pages. 2040 - 1150 = 890. Mirella read 890 more orange pages than purple pages. The answer is 890.
Question: Allen is 25 years younger than his mother. In 3 years, the sum of their ages will be 41. What is the present age of Allen's mother?
Answer: In 3 years, the sum of their present ages will be added by 3 (from Allen) + 3 (from her mother) = 6. So, the sum of their present ages is 41 - 6 = 35. Let x be the present age of Allen's mother and x - 25 be the present age of Allen. So the equation using the sum of their present ages is x + x - 25 = 35. By combining like terms, the equation becomes 2x = 60. Hence, Allen's mother is x = 60 / 2 = 30 years old now. The answer is 30.
[Question]A supermarket has pints of strawberries on sale. They sold 54 pints and made $216, which was $108 less than they would have made selling the same number of pints without the sale. How many more dollars does a pint of strawberries cost when not on sale?
[Answer]On sale, a pint of strawberries costs 216 / 54 = $4. The supermarket would have made 216 + 108 = $324 if the strawberries were not on sale. Thus, a pint of strawberries not on sale costs 324 / 54 = $6. Hence, a pint of strawberries costs 6 - 4 = $2 more when not on sale. The answer is 2.
Q: Jackson wants to go on a shopping spree, so his mom says she will give him some spending money if he does extra chores. She promises $5 per hour spent on chores. Jackson spends 2 hours vacuuming, and decides to do this twice. He also spends 0.5 hours washing dishes, and three times as long cleaning the bathroom. How much spending money has Jackson earned?
A: Jackson spent a total of 2 * 2 = 4 hours vacuuming. This means he earned 4 * $5 = 20 dollars from vacuuming. He earned 0.5 * $5 = 2.5 dollars from washing dishes. Cleaning the bathroom took three times as long as the dishes, so he spent 0.5 * 3 = 1.5 hours in the bathroom. This means he earned 1.5 * $5 = $7.5 from cleaning the bathroom. In total, he has earned $20 + $2.5 + $7.5 = $30. The answer is 30.
Question: There are 7 trucks that have 20 boxes. There are 5 trucks that have 12 boxes. Each box holds 8 containers of oil. If all of the oil is evenly redistributed onto 10 trucks, how many containers of oil will each truck have?
Answer: Boxes of oil = 7 * 20 + 5 * 12 = 200 boxes. Containers of oil = 200 boxes * 8 containers = 1600 containers of oil. 1600 / 10 = 160. Each truck will carry 160 containers of oil. The answer is 160.
Q: Fred had 212 sheets of paper. He received another 307 sheets of paper from Jane and gave Charles 156 sheets of paper. How many sheets of paper does Fred have left?
