I'm guessing you are trying to find out how many water bottles are in each case. So to find this out you divide the number of water bottles by the number of cases and you get your anwer.
162/9 = 18
So there are 18 bottles in a case
162/9 = 18
So there are 18 bottles in a case
18 bottles per case, I think this is the answer you are looking for :)
