Scoresby Inc. tracks the number of units purchased and sold throughout each year but applies its inventory costing method at the end of the year, as if it uses a periodic inventory system. Assume its accounting records provided the following information at the end of the annual accounting period, December 31.

Transactions	Units			Unit Cost
a. Inventory, Beginning		1,500		$	30
For the year:
b. Purchase, March 5		7,500			31
c. Purchase, September 19		3,500			33
d. Sale, April 15 (sold for $75 per unit)		2,100
e. Sale, October 31 (sold for $78 per unit)		6,500
f. Operating expenses (excluding income tax expense), $393,000

Compute the cost of ending inventory and cost of goods sold under (a) FIFO, (b) LIFO, and (c) weighted average cost
