Philip Arellano · Answer 1

First calculate the total price of the car alarm

P = 325 + 0.12 (325)

P = $ 364 is the total prize of the car alarm

then calculate the discounted price

35%-off sale

P = 364 (1 - 0.35)

P = 364 (0.65)

P = $ 236.6

$ 100 coupon

P = 364 - 100

P = $ 264

so it is better to have the 35%-off sale

so the answer is A
