To find the answer, we first need to convert the products to the same unit:
1 gallon = 128 oz
We can then find which is a better deal by comparing the how much ouncesa dollar can buy.
A dollar can buy:
128÷7
=18.285..
≈18.3 oz
The total amount of ounces for eight box of apple juice:
4.32×8
=34.56 oz
For boxes of apple juice,a dollar can buy:
34.56÷2.39
=14.46..
≈14.5 oz
As the volume of a gallon apple juice is higher than boxes if apple juice (18.3>14.5), a gallon of apple juice is a better deal.
Hope it helps!
