[Question]Two boxes for carrying oranges with a capacity of 80 and 50 were filled with 3/4 and 3/5 of the way full with oranges, respectively. Calculate the total number of oranges the boxes have together.
[Answer]For the box with a capacity of 80, if it was 3 / 4 full with oranges, it had 3 / 4 * 80 = 60 oranges. The second box, with a capacity of 50, was 3 / 5 full with oranges, which totals 3 / 5 * 50 = 30 oranges. Together, the two boxes have 60 + 30 = 90 oranges. The answer is 90.

Question: A book library charges fifty cents per day on any book borrowed by its members to read outside the library's premises. At the start of May, Celine borrowed three books from the library to read at home for her upcoming examinations. If she returned one book 20 days after borrowing it, and the other two stayed at her house until the end of May, calculate the total amount of money that she paid at the library for lending the three books.
Answer: Celine was charged $0.50 * 20 = $10 for the book she returned to the library after 20 days. If the other two books stayed at her house until the end of May, she paid 31 * $0.50 = $15.5 for each book. For the two books that stayed at her house until the end of May, Celine paid $15.5 * 2 = $31. For the three books, Celine paid $31 + 10 = $41. The answer is 41.
[Question]Pauly is making ice cubes. He needs 10 pounds of cubes. He knows that 2 ounces of water make 1 cube and each cube weighs 1/16th of a pound. It takes him 1 hour to make 10 cubes. Every hour his ice maker run costs $1.50. Every ounce of water costs $0.10. How much will it cost to make all the ice?
[Answer]He needs 160 ice cubes because 10 / (1 / 16) = 160. It will take him 16 hours because 160 / 10 = 16. His ice maker will cost $24 to run because 16 x 1.5 = 24. He will need 320 ounce of water because 160 x 2 = 320. This will cost him $32 because 320 x .1 = 32. It will cost in total $56 to make all the ice because 24 + 32 = 56. The answer is 56.

Question: Mr. Lu owns a computer store. For last month, half of their sales are laptops, one-third are netbooks, and the rest are desktop computers. If Mr. Lu's store was able to sell a total of 72 computers, how many of them are desktop computers?
Answer:
There were 72 / 2 = 36 laptops sold. There were 72 / 3 = 24 netbooks sold. So, there were a total of 36 + 24 = 60 laptops and netbooks sold. Thus, 72 - 60 = 12 desktop computers were sold last month. The answer is 12.
