The answer is the pack of 3 boxes of juice as 12 is 4 times 3 so $1.09 will need to be multiplied by 4. This equals $4.36. While the 12 pack is way too expensive. Then the 24 boxes with costing of 8.79 is more expensive than the first one. So the 3 pack of boxes of juice costing 1.09 is least expensive.
