Could anyone explain the solution for the denominator to problem two number IV from Quiz 3?  I didn't quite catch the explanation in class.

You may have figured it out already (not sure for which part you needed an explanation the most), but below is the formula I have for the denominator (**Please correct me if I'm wrong!).

tau*P + ceil(P/m)*ceil(N/P)*t    

where,
tau = an overhead incurrs per addition of a process
P = # of process(es)
m = # of processor(s)
N = # of jobs (tasks)
t = the time requierd per job
