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.
