**Reiny**, Wednesday, February 18, 2009 at 12:00amyou have two functions:

cost1 = .52x

cost2 = .44x + 1.2 , where x is the number of prints

the costs are equal when

cost 1 = cost2 , or

.52x = .44x + 1.2

solving this you get x = 15

so try 16 in each equation to see which is the cheaper.

**Brett**, Wednesday, February 18, 2009 at 12:08amSo basically the answer would be x>15? Does this make sense considering that 16 is greater than 15? Thanks for the help!
