Question

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)

Jennifer wants to purchase a book but only has $62.10 to spend. What is the maximum number of pages she can have in her book?

x = ______________________ pages

Numerical Answers Expected!

Answer 1

62.10 = (20 0.5x) 0.15(20 0.5x)

Distribute
62.10 = (20 0.5x) 3 0.075x

Combine like terms
62.10= 23 0.575x

Subtract 23 from both sides
39.10 = 0.575x
0.575x = 39.10

Divide both sides by 0.575
x = 68
