Q: Galileo is currently renting a car that costs $20 per month. He is planning to buy a brand new car that costs $30 per month. If Galileo will have to pay for the new car for a year, how much will be the difference if he gets the brand new car instead of renting a car?
A: Galileo pays $20 x 12 = $240 for renting a car every year. He will pay $30 x 12 = $360 for the brand new car for a year. Therefore the difference between a new car and a refurbished car is $360 - $240 = $120. The answer is 120.

[Question]When Suzy the librarian sat at her desk on Wednesday morning, she had 98 books ready for checkout. The same day, 43 books were checked out. The following day, 23 books were returned, but 5 books were checked out. On Friday, 7 books were returned. How many books did Suzy have?
[Answer]When 43 books were checked out on Wednesday, Suzy remained with 98 - 43 = 55 books. After 23 books were returned on Thursday, she ended with 55 + 23 = 78 books.
