Question

Tosin is filling new bookcases at a library. The books are not all the same thickness, but Tosin knows that generally between 25 and 40 books will fit per shelf. If there are 24 books, what is the difference between the maximum and the minimum number of shelves that will be used ?

Answer 1

The difference is 0

Step-by-step explanation:

Generally, between 25 and 40 books will fit per shelf. Since 24 is less than 25, we can say that 24 books will fit on one shelf, so the minimum and the maximum number of shelves that will be used is 1. Therefore, the difference is:

Maximum - Minimum = 1 - 1 = 0
