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 $500$ units @ $$18=$ $$9,000$

January $8$ Purchase $480$ units @ $$20=$ $$9,600$

January $12$ Sale $880$ units @ $$70$

January $17$ Purchase $540$ units @ $$22=$ $$11,880$

January $23$ Sale $370$ units @ $$70$

January $28$ Purchase $600$ units @ $$24=$ $$14,400$

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