Step-by-step explanation:

To answer this, we just need to divide the price of a gallon by the amount of ounces in a gallon.

When we do this, we get the price of an ounce, or one serving.

There are 128 fluid ounces in a gallon.

$3.48/128=0.02718 ... or 0.03.

The amount of milk for one portion, or one ounce, costs 3 cents.
