Q: 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?
A: 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. However, 5 books were checked out on the same day meaning that 78 - 5 = 73 books were left. After 7 books were returned on Friday, Suzy had 73 + 7 = 80 books. The answer is 80.
