Answer:
y=12x
Explanation:
Since there are 12 bottles in each box, the total number is the number of boxes multiplied by 12.
For example, buying 1 box will give you 12 bottles (1x12) and buying 2 boxes would give you 24 (2x24).
Therefore the equation of the total number of bottles if you buy x boxes is:
y=12x
