As the number of pages in a photo book increases, the price of the book also increases. there is an additional shipping charge of 15%. the price of a book can be modeled by the equation below, where p = the price of the book, 20 is the printing charge, 0.5 is the charge per page, and x = the number of pages:

p = (20 + 0.5x) + 0.15(20 + 0.5x)
