A company purchased 300 units for $60 each on January 31. It purchased 150 units for $25 each on February 28. It sold a total of 250 units for $70 each from March 1 through December 31. If the company uses the weightedaverage inventory costing method, calculate the amount 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.)
