Answer:
The correct answer is A.
Explanation:
Giving the following information:
Beginning finished goods inventory of $20,000
The cost of goods manufactured during the month was $120,000
Ending finished goods inventory was $50,000
To calculate the cost of goods sold, we need to use the following formula:
COGS= beginning finished inventory + cost of goods manufactured - ending finished inventory
COGS= 20,000 + 120,000 - 50,000= $90,000
