we started of by assuming that number of eggs would only be bought in "Dozens" . Like if example i am purchasing "x" eggs , so the total number of dozens are x/12. We can take x/12 also in place of x, but that would unnecessarily complicate the solution. So, It would be better if we take total number of eggs in "Dozens" as cost is also provided per dozen and not on Individual eggs.
