Answer

Explanation:

Step1: Calculate cost of two 64 - ounce cartons

The cost of one 64 - ounce carton with a unit price of 5.1 cents per ounce is $64\times5.1$ cents. The cost of two cartons is $2\times64\times5.1= 2\times326.4 = 652.8$ cents.

Step2: Calculate cost of 128 - ounce jug

The 128 - ounce jug has a unit price of 4.8 cents per ounce. So its cost is $128\times4.8=614.4$ cents.

Step3: Calculate the savings

The savings is the difference between the cost of two cartons and the cost of the jug, which is $652.8 - 614.4=38.4$ cents. Since 1 dollar = 100 cents, in dollars, it is $\frac{38.4}{100}=0.384\approx0.38$ dollars.

Answer:

$0.38$ (corresponding to the first option)
