Exercise 6: A product at Macy's is priced to sell at $500 per unit. Macy's buys it from the supplier at $300 per unit. Each unsold unit has a salvage value of $200. Demand is expected to be between 30 and 35 units for the week. The demand probabilities and the associated cumulative probability distribution for this case are demonstrated below: Units demanded Probability of the demand Cumulative probability 30 31 ordered? 32 33 34 35 What is the optimal 0.10 0.15 0.25 0.25 0.15 0.10 0.10 0.25 0.50 0.75 0.90 1.00 rate that minimizes Macy's inventory costs?
