A company is planning for its financing needs and uses the basic fixed- order-quantity inventory model. Which of the following is the total cost (TC) of the inventory given an annual demand of 10,000, setup cost of $32, a holding cost per unit per year of $4, an EOQ of 400 units, and a cost per unit of inventory of $150? None of these $1,501,600 $1,498,200 $499,313 $500,687

37. A. $1,501,600 Q = 400. Average Inventory = Q/2 = 200. Holding cost/year = $4. Thus, annual holding cost = $800. Annual set-up cost = 10,000/400 = 25 x $32 = 800. Demand x cost per unit = 10,000 x $150 = 1,500,000. Hence, TC = $1,500,000 + 800 + 800 = $1,501,600. 16. Which of the following is a principle of work center scheduling? Reschedule every day.
