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= (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?

Answer 1

This time you have to plug in the 62.10 to the P and solve for x.

 I know that the new equation is now62.10=(20+0.5x)+0.15(20+0.5x)

okay so, x equal 68, the number of pages .
