Given the following:

	Number purchased	Cost per unit			Total
January 1 inventory	43	$	4		$	172
April 1	63		7			441
June 1	53		8			424
November 1	58		9			522
	217				$	1,559

a. Calculate the cost of ending inventory using the weighted-average method (ending inventory shows 64 units). (Round the "average unit cost" and final answer to the nearest cent.)

Cost of ending inventory $

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

Cost of goods sold $

From the following, calculate the cost of ending inventory and cost of goods sold for the FIFO method, ending inventory is 53 units. (Round your answers to the nearest cent.)
