Answer:
4 bottles per pack
Explanation:
This is a quick answer to find! We need to divide how many total bottles there are by how many value packs were purchased. This will work with any of the given pairs.
Divide 8 by 2 and you will get an answer of 4 bottles per value pack. As I previously stated, this will work with any of the other pairs, like so:
8 / 2 = 4
28 / 7 = 4
44 / 11 = 4
52 / 13 = 4
Hope this helps!
