Answer:
a. Increase $1,000
Step-by-step explanation:
The computation is shown below:
Decline in value of inventory is
= $800,000 - $779,000
= $21,000
Now
Gain on Future contract at year end is
= $800,000 - $780,000 = $20,000
So,
Net gain or (loss) is
= $20,000 - $21,000
= ($1,000)
As it can be seen that the cost of goods sold rise by $1,000
Hence option A is correct.
