Enter an inequality that represents the description, and then solve. Toni can carry up to 24 lb in her backpack. Her lunch weighs 1 lb, her gym clothes weigh 3 lb, and her books (b) weigh 4 lb each. How many books can she carry in her backpack?

24 - ( 1+3 ) = 20.
20 + b(book weight; unknown) = answer

Since 4 x 5 is 20, the answer is that Toni can carry 5 books.
