Explanation:

a) Data and Calculations:

Date    Transaction                 Units   Unit Cost    Total

Jan. 1   Beginning inventory      9            $12        $108

May 5, Purchases                    28            $16         448

July 16 Purchases                    19            $20        380

Dec. 7, Purchases                   24            $24        576

Dec. 31 Total                           80                        $1,512

Dec. 31 Ending inventory       30

Dec. 31 Sales                          50

a. The cost of goods sold under FIFO:

Jan. 1   Beginning inventory      9            $12        $108

May 5, Purchases                    28            $16         448

July 16 Purchases                    13            $20        260

Cost of goods sold                                               $816

b. The cost of goods sold under LIFO:

May 5, Purchases                      7            $16          112

July 16 Purchases                    19            $20        380

Dec. 7, Purchases                   24            $24        576

Cost of goods sold                                           $1,068

c. Average unit cost:

= Total cost/Total units

= $18.9 ($1,512/80)

d. The cost of goods sold under average-cost:

= $945 (50 * $18.90)
