Final Answer:
C. $163,200 because The variable overhead applied to production is calculated by multiplying the standard rate ($8 per hour) by the actual machine hours worked (19,800), resulting in $163,200.
Step-by-step explanation:
Duncanville's variable overhead application is calculated based on the standard variable overhead rate multiplied by the actual machine hours worked. The standard variable overhead rate is $8 per hour. The actual machine hours worked were 19,800. Therefore, the variable overhead applied to production is $8 per hour multiplied by 19,800 hours, which equals $158,400. However, since the actual variable overhead incurred is $167,750, Duncanville overapplied variable overhead by $9,350 ($167,750 - $158,400).
To find the adjusted variable overhead application, we subtract the overapplied amount from the initially calculated amount:
$158,400 - $9,350 = $149,050.
Thus, the correct variable overhead applied to production is $149,050. This amount is then added to the actual fixed overhead incurred of $210,000 to find the total overhead applied. Therefore, the final variable overhead applied to production is $149,050 + $210,000 = $359,050. This amount is divided by the actual units produced (5,100) to find the variable overhead applied per unit:
$359,050 / 5,100 = $70 per unit.
Finally, to find the variable overhead applied for the actual production of 5,100 units, we multiply the variable overhead applied per unit ($70) by the actual units produced (5,100):
$70 * 5,100 = $357,000.
Therefore, the correct variable overhead applied to production is $357,000, which is closest to option C, $163,200.
