c. Sale (\$5 each) &   (160)   & \\
d. Sale (\$5 each) &   (700)   & \\
\hline
\end{tabular}>Required:
Compute the amount of   (a)   goods available for sale,   (b)   ending inventory, and (c) cost of goods sold at December 31 under each of the following inventory costing methods (show computations and round to the nearest dollar):

2. First-in, first-out.
3. Last-in, first-out.
4. Specific identification, assuming that the first sale was selected twofifths from the beginning inventory and three-fifths from the purchase of January 30. Assume that the second sale was selected from the remainder of the beginning inventory, with the balance from the purchase of May   1 .
