Anita has written a book of tips on staying healthy. Each book weighs 15 lb. If she packs 12 books in a box for shipping, what will be the shipping weight, excluding the box? Convert the answer to a mixed number. (1 point)
The total weight of the books is 15 lb/book * 12 books = <<15*12=180>>180 lb.
The weight in mixed number form is 180 lb / 1 lb = 180.
