Write an algebraic expression for the situation. Define the variable, then evaluate the expression for the amount given. Andrea wants to buy a photo book from an online photo printing service. The book costs $14.98 plus $0.39 for each photo printed in the book. How much will she pay if she wants to have 35 photos in the book?
+128474
Let N be the number of photos
The total cost C(N) is given by :
14.98 + .39N
And when N = 35, we have
C (35) = 14.98 + .39 (35) = $ 28.63
use the distributive property to rewrite the expression in its equivalent form
(500n + 300m -100) / -100
