Sales of Comfort are relatively constant as the past 10 weeks of data indicate. Each case of Comfort costs Ali OMR10 and a 14% annual holding cost rate is used. The cost to prepare a purchase order for is OMR12. The lead time for a delivery of Comfort has averaged 4 working days. Lead time demand has been estimated as having a normal distribution with a mean of 80 cases and a standard deviation of 10 cases.
