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 of a book can be modeled by the equation below where p equals the price of the book 20 is there printing charge and 0.5 is the charge per page and the x equals the number of pages: p=(20+0.5) + 0.15(20+0.5 jennifer wants to purchase a book but only has $62 .10 to spend what is the maximum number of pages she could have in her book? x= numerical answer ! anyone

Plug in instead of P $62.10. Then we get
62.1 = (20 + 0.5x) + 0.15(20+0.5x)
62.1 = 20 + 3 + 0.5x + 0.075x
0.575x = 39.1
x = 68
So, x = 68 pages.

The equations that best describe the given condition are also presented above.
                                        6x + 6y = 7.5
                                        10x + 5y = 8.75
The values of x and y from the equations are calculated to be 0.5 and 0.75, respectively. Thus, the cost of each apple is $0.5.
