Answer: The correct answer is "B. $2,160."
Explanation: First we must calculate the total costs
Total cost = Goods in process inventory + Direct materials + Direct labor + Overhead.
Total cost = $5400 + $21600 + $16200 + $10800 = $ 54000.
Then the total transferred out =
Total transferred out = Total cost - units in the final inventory of goods in process.
Total transferred out = $54000 - $4590 = $49410.
Now we must know the beginning goods in process transferred out =
BGIP Transfered = Total transfered out - units started and completed.
BGIP Transfered = $49410 - $41850 = $7560
And finally we calculate the cost to complete the begining goods in process inventory which is =
Cost to complete BGIP = BGIP transfered out - Goods in Process Inventory Balance.
Cost to complete BGIP = $7560 - $5400 = $2160
