Answer:
28%
Step-by-step explanation:
start with $46 = 100% of starting price
coupon = 40% off starting price
40% off of 100% = 100% - 40% = 60% of starting price = price after coupon
60% = 0.6
60% of starting price = price after coupon = 0.6 * $46 = $27.6
then, a 20% processing fee is applied to the price after the discount
new price = $27.6 = 100% of new price
fee = 20% added to new price
20% added to new price = 100% + 20% = 120% of new price
120% = 1.2
final price = price after fee = 120% of new price = 1.2 * $27.6 = $33.12
change in percentange = (original price - new price) / original price * 100
= ($46 - $33.12) / $46 * 100 = 28%
