Jack has a stack of books that is 12 inches thick. He knows from experience that 80 pages is one inch thick. If he has 6 books, how many pages is each one on average?
A step-by-step solution is:
160
There are 960 pages because 80 x 12 = 960.

Each book is 160 pages because 960 / 6 = 160.

.

So, the answer is 160
