128 ounces in a gallon

The pack is 33.84 ounces in total

gallon for 7=18 cents per ounce

pack for 2.39 is. 07 cents per ounce

So the pack is a better deal

Yeah, the pack is a better deal. A gallon is only 128 oz which costs $7. While the pack of juice is 33.84 oz, if you buy three of the juice packs they would then weigh 135.36 oz at the cost of $7.17. Which is only 17 cents more than a gallon.
