If X = 2, and Y = 4:
2(2) + 3(4) - 2 - (8 + 1) = 5
4 + 12 - 2 - 9 = 5
16 - 2 - 9 = 5
14 - 9 = 5
= 5
(2) + 3(4) - 9 = 5
2 + 12 - 9 = 5
14 - 9 = 5
= 5
So, your answer would be 'C' X + 3Y - 9
For the first one the price per ounce is:
$4.56/15oz=0.304 dollars per ounce, which rounds to 0.3
For the second:
$5.98/25oz=0.2392 dollars per ounce, which rounds to 0.24
The second is the cheapest price per ounce and rounds to $0.24/oz so 0.24 is the answer
