A company purchased 400 units for $50 each on January 31. It purchased 150 units for $30 each on February 28. It sold a total of 200 units for $60 each from March 1 through December 31. If the company uses the weighted average inventory costing method, calculate the cost of ending inventory on December 31. (Assume that the company uses a perpetual inventory system. Round any intermediate calculations two decimal places, and your final answer to the nearest dollar.) OA. $8.907 OB. $14,000 OC. $24,500 OD. $15,593 C
