toni can carry 18 lb in her backpack. Her lunch weighs 1 lb, her gym clothes weigh 2 lb, and her books (b) weigh 3 lb each. How many books can she carry in her backpack?

Respuesta :

2 plus 1 is 3 so that means 18 minus 3 equals 15 lbs left so she can carry 5 books since 5 times 3 is 15

The answer is 5 so it will be written as c=5
