Answer:
$640,000
Step-by-step explanation:
In order to compute the cost of goods sold, first we have to determine the cost of goods manufactured which is shown below:
Cost of goods manufactured = Work in process, September 1 + Manufacturing cost - Work in process, September 30
where manufacturing cost equal to
= Purchase of direct material + Direct labor cost + Manufacturing Overhead cost
= $200,000 + $120,000 + $325,000
= $645,000
So the Cost of goods manufactured would be
= $80,000 + $645,000 - $90,000
= $635,000
And, the cost of goods sold would be
= Finished goods, September 1 + Cost of goods manufactured - Finished goods, September 30
= $70,000 + $635,000 - $65,000
= $640,000
