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)

Respuesta :

Say you started at 1oo pages and went down by 10s. P=(20+.5*70) + .15(20+.5*70). P=(20+35) + (55*.15) P=55+5.25 So finally, P= 60.25, which is under the limit of $62.10.
