If Millennium chooses to order 100 cases each time, what is the sum of the ordering and holding costs incurred by each case sold? (Do not round intermediate calculations. Round your answer to the nearest whole number.) If Millennium is restricted to ordering in multiples of 50 cases (e.9.50,100, d. 150, etc.), how many cases should it order to minimize its annual ordering and holding costs?
