Alphabet Company, which uses the periodic inventory method, purchases different letters for resale. Alphabet had no beginning inventory. It purchased A thru G in January at $$2\mathrm{.}50$ per letter. In February, it purchased H thru L at $$4\mathrm{.}50$ per letter. It purchased M thru R in March at $$5\mathrm{.}50$ per letter. It sold A$,$ D$,$ E$,$ H$,$ J and N in October. There were no additional purchases or sales during the remainder of the year.

If Alphabet Company uses the specific identification method, what is the cost of its ending inventory?
