Sally's work would be correct
We know that Clara bought 16 cases of water bottles
In each case, there are 12 water bottles
So when you multiply 16 by 12, she would have a total of 192 water bottles.
In Sally's work, you would see her equation is:
b/12 = 16
In order to get b by itself, you would have to multiply both sides by 12. Hence, you're multiply 16 by 12, which what you're suppose to do in order to get the total amount of bottles, or b.
Therefore, your answer would be Sally's work.
