A company purchased 1,000 units of a product at \(\$ 12.00\) and 2,000 units at \(\$ 13.20\). It sold all of these units at \(\$ 18.00\) each at a time when the current cost to replace the units sold was \(\$ 13.80\). Compute the amount of gross margin under FIFO that LIFO supporters would call inventory, or paper, profits.
