c) The phone case you want to buy is marked down 30%, and you have a 25% off
coupon. You pay $42.00. Can this equation be used to find the original price of the
phone case? If so, what is the original price of the item? Explain. (5 points)
(0.7c) = 42
Answer: Yes you can find the original price which is 570 Explanation: Since it is already marked down 30% you would calculate that 42/.30=140 Then because you have a 25% coupon you would calculate 140/.25=560
