Answer:
See below
Explanation:
a. Given that the overhead application rate is $21.40 per direct labor hour and total labor hours used during the period are 8,250 hours
Overhead applied = $21.40 × 8,250
Overhead applied = $176,550
Actual overhead incurred = $172,500
Then, the manufacturing overhead is over applied for the period by $4,050
I.e
= Overhead applied - Actual overhead incurred
= $176,500 - $172,500
= $4,050
b. With regards to the above, if the over applied overhead is closed out to cost of goods sold, it means that the cost of goods sold amount would decrease . The reason is that since cost of goods sold is deducted from revenue to determine gross margin, a reduction in cost of goods sold would bring about an increase in the company's gross margin for the period by $4,050
