Question

What is the unit price of a quart of milk for $0.89

A. 3.56/oz
B. $4/lb
C. $3.56/gallon
D. $3/half gallon

Answer 1

.89x4 is 3.56, 4 quarts to a gallon. Answer is D

Answer 2

Option C. $3.56 per gallon

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 =
`(0.89)/(32)`

= $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 =
`(0.89)/(2.20)`

= $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 =
`(0.89)/(0.25)`

= $3.56

Therefore, this option is the correct option.

D. $3/ half gallon

1 quart = 0.25 gallon

1 gallon milk will cost =
`(0.89)/(0.25)`

= $3.56

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

Therefore, option C. is the correct option.
