Question: John's camera broke so he decided to rent one for 4 weeks. It was a $5000 camera and the rental fee was 10% of the value per week. His friend who was there when it broke agreed to pay 40% of the rental fee. How much did John pay?
Answer: The rental fee is 5000 * .1 = $500 per week. So it cost 500 * 4 = $2000. His friend pays 2000 * .4 = $800. So he pays 2000 - 800 = $1200. The answer is 1200.

Q: Sarah is checking out books from the library to read on vacation. She can read 40 words per minute. The books she is checking out have 100 words per page and are 80 pages long. She will be reading for 20 hours. How many books should she check out?
A: Each book has 8,000 words because 100 x 80 = 8,000. She can finish each book in 200 minutes because 8,000 / 40 = 200. She will be reading for 1,200 minutes because 20 x 60 = 1,200. She needs to check out 6 books because 1,200 / 200 = 6. The answer is 6.
