Answer:
The cost per gallon of the juice = $9
Explanation:
Given
The price of eight 4.23 ounce juice boxes is $2.39
We should know that: 1 Gallon = 128 Ounces
1 juice boxes = 4.23 ounce
So, juice boxes per gallon = 128/4.23 = 30.26
But The price of 8 juice boxes is $2.39
So, the price of 1 gallon = (30.26/8) * 2.39 = 9.04 ≈ $9
So, the cost per gallon of the juice = $9
