Chapter 11 - Assignment 5 1. The local supermarket buys lettuce daily to ensure fresh produce. Each morning, any lettuce left from the previous day is sold to a dealer that resells it to farmers who use it to feed their animals. This week the supermarket can buy fresh lettuce for $11.00 a box. The lettuce is sold for $24.00 a box and the dealer that sells old lettuce is willing to pay $3.00 a box. Past history says that tomorrow's demand for lettuce averages 275 boxes with a standard deviation of 45 boxes. How many boxes of lettuce should the supermarket purchase tomorrow? 2. Ray's Satellite Emporium wishes to determine the best order size for its best-selling satellite dish (model TS111). Ray has estimated the annual demand for this model at 800 units. His cost to carry one unit is $120 per year per unit, and he has estimated that each order costs $19 to place. Using the EOQ model, how many should Ray order each time? (Round your answer the nearest whole number.) 3. The annual demand for a product is 14,700 units. The weekly demand is 283 units with a standard deviation of 80 units. The cost to place an order is $33.00, and the time from ordering to receipt is eight weeks. The annual inventory carrying cost is $0.20 per unit. Find the reorder point necessary to provide a 99 percent service probability. (Round your answer to the nearest whole number.) 4. Charlie's Pizza orders all of its pepperoni, olives, anchovies, and mozzarella cheese to be shipped directly from Italy. An American distributor stops by every six weeks to take orders. Because the orders are shipped directly from Italy, they take five weeks to arrive. Charlie's Pizza uses an average of 200 pounds of pepperoni each week, with a standard deviation of 22 pounds. Charlie's prides itself on offering only the best-quality ingredients and a high level of service, so it wants to ensure a 90 percent probability of not stocking out on pepperoni. Assume that the sales representative just walked in the door and there are currently 400 pounds of pepperoni in the walk-in cooler. How many pounds of pepperoni would you order? (Round your answer to the nearest whole number.)
