Company X ends the month with two jobs still in progress. Job 5 has $10000 of materials,

$2000 of direct labor and $4964 of manufacturing overhead allocated. Job 6

was $30000 of materials, $2000 of direct labor and $10000 of manufacturing

overhead allocated. The cost of goods sold for the month was $40000 and of that

30% was overhead. There were no finished goods in stock as the month ends. If

the manufacturing overhead is underallocated by $10000, which of the following

choices would be the correct way to prorate it, assuming the proration is based

on the allocated overhead in the ending balances of work-in-process, finished

goods, and cost of goods sold?
