a. Calculate the cost of ending inventory using the weighted-average method (ending inventory shows 70 units). (Round the "average unit cost" and final answer to the nearest cent.)

b. Calculate the cost of goods sold using the weighted-average method. (Round your intermediate calculations and final answer to the nearest cent.)
