one photo shop charges 0.26 per print. another shop charges 3.25 set up fee and 0.21 per print. how many prints would u need to develop so that the cost is the same at either shop

Answer 1

.26p = .21p + 3.25 solve for p

.05p = 3.25

p = 3.25/.05 = .65/.01 = 65 prints make the costs equal= $16.90
