Answer:
Cost of goods sold is $9,620
Explanation:
First step prepare the Cost of Goods Manufactured Account
Direct materials                $ 9,100
Direct labor                   $ 2,800
Manufacturing overhead applied  $ 4,800
Total Manufacturing Costs       $16,700
Add Opening Work In Process    $ 5,800
Less Closing Work In Process     $ 0
Cost of Goods Manufactured     $22,500
Next we need to calculate the cost of goods sold as follows :
Opening Finished Goods Inventory         $0
Add Cost of Goods Manufactured       $22,500
Less Closing Finished Goods Inventory   ($12,500)
Cost of goods sold                    $10,000
Less Over-applied Overheads             ($380)
Adjusted Cost of goods sold             $9,620
Finished Goods Inventory = $22,500 × 100/180
                      = $12,500
Thus Cost of goods sold is $9,620
