Answer:
$880,000
Explanation:
The amount of over-applied or under-applied overheads is usually used to adjust the Cost of Goods Sold amount.
Since, Applied Overheads ($300,000) > Actual Overheads ($280,000), we say overheads are over-applied.
Over-application = $300,000 - $280,000 = $20,000
Adjusted Cost of Goods Sold :
Cost of Goods Sold before adjustments $900,000
Less over-applied overheads ($20,000)
Cost of Goods Sold $880,000
Therefore, after adjusting for the overapplied overheads the cost of goods sold amounts to $880,000
