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 =

                                                  = $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  =  

                                                   = $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 =

                                                        = $3.56

Therefore, this option is the correct option.

D. $3/ half gallon

1 quart = 0.25 gallon

1 gallon milk will cost =

                                          = $3.56

Now half gallon milk will cost = $1.28 ≠ $3 per gallon

Therefore, option C. is the correct option.
