Let us imagine that your math 123 book cost $45 to print. how much does it cost per page? (hint: you will need information about your book to calculate this! )

45/p where p is the number of pages of the book.

Step-by-step explanation:

To know the price per page of printing, we need to know the total number of pages of the book.

Let's call p the number of pages of the book and x the cost per page. Now we are going to do a proportion and will solve for x

Therefore, the price per page will be 45 divided by the number of pages of the book.
