Accepted Solution
A:
Answer:Brand CStep-by-step explanation:Brand A:Per ounce cost = 3.19/15 = $0.21Brand B:To get 1 oz cost, we put x = 1 into the equation, thusy = 0.18 xy = 0.18(1)y = 0.18Per ounce cost = $0.18Brand C:Per oz cost of 10 oz @ 1.60 = 1.60/10 = $0.16Per oz cost of 24 @ 3.84 = 3.84/24 = $0.16Per oz cost of 27 at 4.32 = 4.32/27 = $0.16So, we can see that the best buy is Brand C, because it costs less [0.16 per oz].
