Answer:
The correct answer is $210.
Explanation:
According to the scenario, the computation of the given data are as follows:
01-Oct Begin In     15.00   $12.00   =  $180.00 Â
05-Oct Purchase     10.00   $13.00   =  $130.00 Â
12-Oct Purchase     20.00   $14.00   =  $280.00
So, If it sells 30 Units,
Then,
Begin In     15.00   $12.00   =  $180.00
Sell           10.00   $13.00   =  $130.00 Â
Sell          5.00   $14.00   =  $70.00
Remaining units   15 units
So, Total value of inventory = Remaining unit × $14
= 15 units × $14
= $210
