Question

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 $3.00 a box. The lettuce is sold for $11.00 a box and the dealer that sells old lettuce is willing to pay $1.10 a box. Past history says that tomorrow's demand for lettuce averages 225 boxes with a standard deviation of 32 boxes. Required: How many boxes of lettuce should the supermarket purchase tomorrow?

Explanation / Answer

Average Daily Demand = 225

Standard Deviation of Daily Demand = 32

Safety Stock = z * SD = 2.045 * 32 = 65 (Assuming 98% service level)

Order Quantity = (225 *1)+65 = 290 boxes
