In its first month of operations, Skysong, Inc. made three purchases of merchandise in the following sequence: (1) 220 units at $10, (2) 440 units at $11, and (3) 420 units at $12.

Assuming there are 140 units on hand, compute the cost of the ending inventory under the (a) FIFO method and (b) LIFO method. Skysong uses a periodic inventory system.

				FIFO
(a)		Cost of the ending inventory		$enter the cost of inventory as per FIFO in dollars

				LIFO
(b)		Cost of the ending inventory		$enter the cost of inventory as per LIFO in dollars
