Answer:
Inventory should be increased (debited) by $3,500.
Step-by-step explanation:
According to the IAS 2, the inventory value should be lower of historical cost or net realizable value
The historical cost is $12,000
And, the net realizable value is
= $9,000 - $500
= $8,500
Since as we can see the lower value is $8,500 but due to increase in realizable value, the historical cost would remain the same i.e $12,000
So the inventory should be increased or debited by $3,500 i.e
= $12,000 - $8,500
= $3,500
