Answer:
73,450 COGS
Explanation:
From the beginning inventory we add up purchase and freight cost and subtract the return made to the suplier and discount and allowance granted.
This will be the total cost available for sale.
Then we subtract the ending inventory to get the COGS
27,000 beginning inventory
+ 78,000 purchases
+ 350 freight-in
- 3,900 return and allowance
- 6,000 discount
95,450 good available for sale
- 22,000 ending inventory
73,450 COGS
The sales return impact the sales revenue not the COGS
