Daily demand for product sample kits is normally distributed with a mean of 35 units and a standard deviation of 4. Supply is virtually certain with a lead time of 9 days. The cost of placing an order is $20, and annual carrying costs for one kit is 25 percent. The price of one kit is $12.50. Assume a year has 365 days.If a 99% service level is desired, what is average inventory on hand? If demand had no variation, what would the reorder point be?

40) PLEASE HELP WITH THIS! Gentle Ben's Bar and Restaurant uses 5,000 quart bottles of an imported wine each year. The effervescent wine costs $3 per bottle and Is served only in whole bottles because it loses its bubbles quickly. Ben figures that it costs $10 each time an order is placed, and holding costs are 20 percent of the purchase price. It takes three weeks for an order to arrive. Weekly demand is 100 bottles (closed two weeks per year) with a standard devlation of 30 bottles. Ben would like to use an inventory system that minimizes inventory cost and will provide a 95 percent service probability. b. At what inventory level should he place an order? Note: Use Excel's NORM.S.IN( function to find the z value. Round z value to 2 decimal places and final answer to the nearest whole number.
