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)

Numerical Answers Expected!

Answer 1

$62.10 minus (15% of $62.10) = P, then solve for 'x'.

Answer 2

68 it is.
if we call (20 + 0,5x)=a then
a + 15a/100= 115a/100
which is
62,1

Answer 3

\[62.10=20+0.5x+3+0.075x\]

Answer 4

hold on i'm so lodt right now

Answer 5

lost*
