Brand C:
Per oz cost of 10 oz @ 1.60 = 1.60/10 = $0.16
Per oz cost of 24 @ 3.84 = 3.84/24 = $0.16
Per oz cost of 27 at 4.32 = 4.32/27 = $0.16

Answer:
D) LM=12; QP=8
Step-by-step explanation:
12/18=(x-1)/(x+3)
cross multiply
12x+36=18x-18
36+18=18x-12x
54=6x
9=x
LM = x+3 = 9+3 = 12
QP = x-1 = 9-1 = 8

Presumably we're supposed to put y in the table. That's not totally clear.
x - 6y = -6
-6y = -x - 6
y = (x+6)/6
x - 3y = -4
-3y = -x - 4
y = (x+4)/3
We wrote them like that because they're a little easier to compute that way.
x y = (x+6)/6 y = (x+4)/3
-4 (-4 + 6)/6 = 2/6 = 1/3 y=(-4+4)/3 = 0
-2 y = (-2+6)/6=2/3 y=(-2+4)/3 =2/3
0 y = (0 + 6)/6 = 1 y=4/3
2 y = 8/6=4/3 y=(2+4)/3=2
4 (4+6)/6=10/6=5/3 y=(4+4)/3=8/3
