A company purchased 200 units for $ 40 each on January 31. It purchased 250 units for $ 30 each on February 28. It sold a total of 250 units for $ 80 each from March 1 through December 31. If the company uses the weightedminusaverage 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.)
