U.S postal service regulations state that a package can be mailed using parcel post rates is it weighs no more that 70 pounds. What is the maximum number of books weighing 12 pounds each that can be mailed in one box using Parcel Post rates

Respuesta :

Divide the limit by the weight of one book to find the number of books allowed.

70/12 = 5.833 books

You cannot send a part of a book, so round down. The answer is 5 books.
