Coupon A: $18 rebate on a $59 printer
Coupon B: 35% off of a $59 printer
With coupon A, the final price is 59-18 = 41 dollars
With coupon B, the final price is 59-0.35*59 = 38.35 dollars
So coupon B offers the lower price. The price difference between the coupon options is $2.65 (41-38.35 = 2.65); meaning that coupon B is the better option by $2.65
