The mega-store chain HG ("Home & Garden") imports decorative planters from Italy. The average weekly demand is 1,000 planters ( if a comma appears, interpret it as a thousand separator). Each planter costs $10 at HG. The cost of capital at HG is estimated at 25%. Each order from Italy costs HG $10,000 (freight, customs, inspection, etc.) Suppose there are 52 weeks in a year.

Refer to the context of the previous question. If the weekly standard deviation of planter demand at HG was 930, the delivery time from Italy was 4 weeks and HG wanted to provide a 90% level of service to its customers, what size should be safety stock?
