At the Copy Shoppe, 18 copies costs $1.08. At that rate, how much will 40 copies cost?

Question

 help!!!!!!

Answer 1

Why don't we determine how much it costs to make one copy? We know that we can produce 18 copies for $1.08. The price for one copy would be 1.08/18 = .06 or 6 cents per copy. If we want to make 40 copies, then the cost would be:

 

40 * 0.06

 

You should be able to determine that, Greysen.

Answer 2

40 copies will cost $2.40
