d. Daily standard deviation 15
Daily variance 225
Lead time variance 900
Lead time standard deviation 30
Service level 0.15
Z cut off 1.036
ROP 287.09
Safety stock 31.09
e. Annual holding & order cost $2,095.29
RonZitron: At the EOQ, the annual order cost equals the annual holding cost. Thus the total of the two is also equal to twice the annual holding cost.
