The correct answer is D.

Explanation:

Giving the following information:

The company based its predetermined overhead rate for the current year on the following dа ta:

Total machine-hours 80,000

Total fixed manufacturing overhead cost $ 312,000

Variable manufacturing overhead per machine-hour $ 2.10

Job T629:

Total machine-hours 200

First, we need to calculate the predetermined overhead rate:

Estimated manufacturing overhead rate = total estimated overhead costs for the period / total amount of allocation base

Estimated manufacturing overhead rate = 312,000/80,000 = $3.9 per machine hour

Now, we can calculate the allocated overhead:

Allocated MOH = Estimated manufacturing overhead rate * Actual amount of allocation base

Allocated MOH=3.9*200 = $780
