Q: 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?
A: 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.

When Haman collected 10 trays and dropped 2 trays, he was left with 10 trays - 2 trays = 8 trays. When he added 7 more trays, the total number of trays became 8 trays + 7 trays = 15 trays. Since each tray contains 36 eggs, the total number of eggs to be sold is 36 eggs / tray * 15 trays = 540 eggs. The answer is 540.
