A consulting firm is trying to determine how to minimize the annual costs associated with purchasing high-quality paper for its printers. Each time an order is placed, an ordering cost of $50 is incurred. The price per ream of printer paper depends on Q, the number of reams ordered, as shown in the file P12_31.xlsx. The annual holding cost is 20% of the dollar value of inventory. During each month, the consulting firm uses 80 reams of printer paper. Determine the optimal order quantity and the number of orders placed each year.
