Sue borrowed 15 books and 6 movies. She returned 8 books. She then returned a third of the movies to the library and checked out 9 more books. How many movies and books does Sue now have? Let's be accurate as possible.
Sue has 15 - 8 = 7 books left after returning at the library. Sue returned 6 / 3 = 2 movies to the library. Sue had 6 - 2 = 4 movies left. Sue had 7 + 9 = 16 books after checking out at the library. Sue has 16 + 4 = 20 movies and books combined.
The answer: 20.
