Answer:

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

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


(45)/(p) =(x)/(1) \\x= (45)/(p)

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