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?

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

(500n + 300m - 100 ) / -100   =

 

-100 ( -5n - 3n + 1)  / -100  =

 

-5n - 3n + 1
