Gentle Ben's Bar and Restaurant uses 6,500 quart bottles of an imported wine each year. The effervescent wine costs $8 per bottle and is served only in whole bottles because it loses its bubbles quickly. Ben figures that it costs $20 each time an order is placed, and holding costs are 35 percent of the purchase price. It takes five weeks for an order to arrive. Weekly demand is 130 bottles (closed two weeks per year) with a standard deviation of 35 bottles. Assume 7 days per week for the calculations.
Ben would like to use an inventory system that minimizes inventory cost and will provide a 99 percent service probability.

b) At what inventory level should he place an order? (Round your answer to the nearest whole number.)
