Answer:
$312
Step-by-step explanation:
The computation of the cost of goods sold under the LIFO method is shown below:
Since the 15 units are sold, so the cost of goods sold is
= December 20 units × price on that date + Remaining units × price on that date
= 12 units × $21 + 3 units × $20
= $252 + $60
= $312
The remaining units is
= 15 units - 12 units
= 3 units
Hence, the cost of goods sold under the LIFO inventory method is $312
