The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.
The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.
The percentage is just like the amount of that value but between 1 to 100 and it is very useful to predict for example if you say 678 then we have to know about the full number also but if you say 80% then it becomes clear.
Given,
Coupon A ⇒
35% off of a $59 printer
35% of 59 = 35(59)/100 = $20.65
So,
Cost of printer = $38.35
Coupon B ⇒
$18 rebate on a $59 printer
18% of 59 = 18(59)/100 = $10.62
So.
Cost of printer = $47.79
Hence, The cost of a printer by coupon A will be $38.35 and by coupon B $47.79 so coupon A will gives Mary to lower price.
