The local supermarket buys lettuce each day to ensure really fresh produce. Each morning any lettuce that is 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?
