If a customer bought an item that had a full price of $775 from a retailer, how much in total will the retailer receive in the end if the customer used a coupon for $125?

a. $775
b. less than $650
c. more than $650 but less than $775
d. $650

x = Original Price = $775

y = Coupon Value = $125 (this is the amount you save)

z = Final Price = x-y = 775 - 125 = 650

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.
