Ty Ty tracks the number of units purchased and sold throughout each accounting period but applies its inventory costing method at the end of each month, as if it uses a periodic inventory system. Assume Ty Ty's records show the following for the month of January. Sales totaled 270 units.

	Date	Units	Unit Cost	Total Cost
Beginning Inventory	January 1	220	$ 85	$ 18,700
Purchase	January 15	480	95	45,600
Purchase	January 24	200	115	23,000

Calculate the cost of ending inventory and cost of goods sold using the (a) FIFO, (b) LIFO, and (c) weighted average cost methods.
