Total: Goods available           370                                       $10,555

         Goods sold                  270                                                        $11,675

Weighted-average cost = Cost of goods available/Units available

= $10,555/370 = $28.527 per unit

Periodic method:

LIFO:

Ending inventory:

Oct. 1      Beginning inventory   70        $26  $1,820

Oct. 9     Purchase                     30          28       840

Total Ending inventory =          100               $2,660

Cost of goods sold = Cost of goods available - Ending inventory

= $10,555 - $2,660 = $7,895

Sales Revenue         $11,675

Cost of goods sold     7,895

Gross profit               $3,780

FIFO:

Ending inventory:
