b) $84,200.
c) $93,200.
d) $141,000.
e) $600,000.

The correct answer is A.

Explanation:

Giving the following information:

Item Drilling Grinding Total

Number of employees 1,000 1,500 2,500

Net sales $ 376,000 $ 564,000 $ 940,000

Cost of goods sold $ 129,200 $ 210,800 $ 340,000

First, we need to calculate the predetermined overhead rate for each  office expense:

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

Salaries= 45,000/2,500= $18 per employee

Depreciation= 31,000/340,000= $0.091 per COGS

Advertising= 65,000/940,000= $0.069 per net sale

Now, we can allocate costs to Drilling:

Salaries= 18*1,000= $18,000

Depreciation= 0.091*129,200= $11,757.2

Advertising= 0.069*376,000= $25,944

Total allocated office costs= $55,701.2

the answer is i don't know
