Bill had to finish a project from work that was to take him 4 days. If he took 6 seven-hour naps in the four days, how long did he spend working on the project? Give the rationale and then the answer.
Let's think step by step. Since a day has 24 hours, the project was to take 24 * 4 = 96 hours. Bill took 6 seven - hour naps during the four days, a total of 6 * 7 = 42 hours. The time he spent working on the project is 96 - 42 = 54 hours.. The answer is: 54.

A tomato plant has 100 tomatoes. Jane picks 1/4 of that number for use in their house. After a week, she goes back and picks 20 more tomatoes, and the following week picks twice that number. What's the total number of fruits remaining on the tomato plant? Give the rationale and then the answer.
Let's think step by step. When she picks 1 / 4 of the number of tomatoes, she goes home with 1 / 4 * 100 = 25 tomatoes. The total number of tomatoes remaining will be 100 - 25 = 75 tomatoes. After picking 20 more tomatoes the following week, the number of tomatoes remaining is 75 - 20 = 55 tomatoes. The next week she picks twice the number she picked the previous week, that is 20 * 2 = 40 tomatoes. The total number of tomatoes remaining after the final picking is 55 - 40 = 15 tomatoes.. The answer is: 15.

Jane plans on reading a novel she borrows from her friend. She reads twice a day, once in the morning and once in the evening. In the morning she reads 5 pages and in the evening she reads 10 pages. If she reads at this rate for a week, how many pages will she read? Give the rationale and then the answer.
Let's think step by step. The number of pages Jane reads in a day is 5 in the morning and 10 in the evening, so she reads 10 + 5 = 15 pages in a day. If she reads for a week she reads for 7 days, so by the end of the week she reads 15 * 7 = 105 pages.. The answer is: 105.
