Answer:
Cost of goods sold should be Increased by $4,000
Explanation:
Overhead allocated to Job 5 = $8,000
Overhead allocated to Job 6 = $10,000
Overhead allocated to cost of goods sold = 40,000 x 30%
= $12,000
Total overhead allocated = Overhead allocated to Job 5 + Overhead allocated to Job 6 + Overhead allocated to cost of goods sold
= 8,000 + 10,000 + 12,000
= $30,000
Overhead allocation percentage of Job 5 = Overhead allocated to Job 5/Total overhead allocated
= 8,000/30,000
= 26.7%
Overhead allocation percentage of job 6 = Overhead allocated to Job 6/Total overhead allocated
= 10,000/30,000
= 33.3%
Overhead allocation percentage of Cost of goods sold = Overhead allocated to cost of goods sold/Total overhead allocated
= 12,000/30,000
= 40%
Under allocated overhead = $10,000
Thus, Under allocated overhead to be allocated to cost of goods sold = Under allocated overhead x Overhead allocation percentage of cost of goods sold
= 10,000 x 40%
= $4,000
Thus, Cost of goods sold should be Increased by $4,000
