Answer:
Option C. $3.56 per gallon
Step-by-step explanation:
The unit price of a quart of milk = $0.89
A. 3.56/oz
1 quart = 32 ounce
Now 32 oz milk will cost = $0.89
Therefore,Cost of 1 oz of milk = [tex]\frac{0.89}{32}[/tex]
= $0.027 ≠ $3.56 per oz
So incorrect option.
B. $4/lb
1 quart = 2.20 lb
2.20 lb milk will cost = $0.89
Therefore, Cost of 1 lb of milk = [tex]\frac{0.89}{2.20}[/tex]
= $0.40 ≠ $4.0 per lb
Therefore, incorrect option.
C. $3.56/gallon
1 quart = 0.25 gallon
0.25 gallon milk will cost = $0.89
Therefore, cost of 1 gallon of milk = [tex]\frac{0.89}{0.25}[/tex]
= $3.56
Therefore, this option is the correct option.
D. $3/ half gallon
1 quart = 0.25 gallon
1 gallon milk will cost = [tex]\frac{0.89}{0.25}[/tex]
= $3.56
Now half gallon milk will cost = $1.28 ≠ $3 per gallon
Therefore, option C. is the correct option.
