Perpetual Inventory Using FIFO

Beginning inventory, purchases, and sales data for prepaid cell phones for August are as follows:

Inventory		Purchases		Sales
August 1	2,200 units at $33	August 10	1,100 units at $35	August 12	1,540 units
		August 20	990 units at $37	August 14	1,320 units
				August 31	660 units

Assuming that the perpetual inventory system is used, costing by the FIFO method, determine the cost of the merchandise sold for each sale and the inventory balance after each sale.
