A company's inventory records indicate the following data for the month of January:

Date	Activities	Units Acquired at Cost	Units Sold at Retail
January 1	Beginning inventory	180 units @ $9 = $1,620
January 5	Purchase	170 units @ $10 = $1,700
January 9	Sale		300 units @ $35
January 14	Purchase	200 units @ $11 = $2,200
January 20	Sale		150 units @ $35
January 30	Purchase	230 units @ $12 = $2,760

If the company uses the LIFO perpetual inventory system, what would be the cost of the ending inventory?
