Answer:
D) $31.
Explanation:
The computation of the predetermined overhead rate is shown below:
Predetermined overhead rate = Estimated manufacturing overhead ÷ estimated direct labor hours
where,
Estimated manufacturing overhead is
= Salary of factory supervisor + Heating and lighting costs for factory + Depreciation on factory equipment
= $37,600 + $22,000 + $5,600
= $65,200
And, the direct labor hours is 2,100
So, the predetermined overhead rate is
= $65,200 ÷ 2,100
= $31
