You have a new client who sells fishbowls online. The fishbowls come in three sizes: Small, medium, and large.

In the past, when supplies appeared to run low, your client has ordered more fishbowls in bulk from a distributor $($Squid Debelius LLC$),$ repackages the fishbowls, and ships individual fishbowls in response to customer orders. Sometimes your new client has been slow to fulfill orders because she didn't have enough fishbowls and, at other times, she had so many fishbowls that she had to store the oversupply in the guest bedroom of her house. The new client suspects that the subjective approach to reordering$---$ordering when she "thinks" supplies are low$---$is unnecessarily costly and inefficient. She is interested in a better bulk ordering system, one where the Squid Debelius LLC order size minimizes costs while meeting customer demand.

Can you help your new client $($as well as keep fishbowl enthusiasts happy$)?$
