Question

Walmart sells to sizes of milk. One contains a half gallon of milk and costs $1.82.
The other contains one gallon of milk and costs $3.68. What is the difference in cost
in dollars per fluid ounce between the two containers.

Answer 1

Answer:

Difference = $0.01

Step-by-step explanation:

Given that:

Cost of half gallon = $1.82

Cost of one gallon = $3.68

First we will convert gallons to ounces.

1 gallon = 128 ounces

half gallon = 64 ounces

Now,

we will find unit rate of both.

Unit rate of half gallon = $\frac{1.28}{64} = \ 0.02$

Unit rate of one gallon = $\frac{3.68}{128} = \ 0.03$

Difference= 0.03 - 0.02 = $0.01

Hence,

Difference = $0.01
