Answer:
$21
Step-by-step explanation:
As we know that
The inventory should be recorded in the books of accounts by applying the lower value of cost or net realizable value
In the given case
The cost is $23
And, the net realizable value is
= Expected selling price - selling cost
= $36 - $15
= $21
So by comparing the cost and net realizable value, the net realizable value contains the lower value i.e $21 and the same is recorded on the balance sheet for inventory
