Answer:
$408,000
Step-by-step explanation:
Mainly there are two types of cost i.e variable cost and the fixed cost. The variable cost is that cost which is change when the production level change whereas the fixed cost is that cost which remains constant whether production level changes or not
So, the variable cost includes indirect material, indirect labor, and factory supplies
And, the fixed cost includes supervision, taxes ,and depreciation expense.
Now the fixed cost would be
= Supervision + depreciation expense + tax
= $50,000 + $60,000 + $10,000
= $120,000
For computing the variable cost, first we have to determine the variable cost per unit which is shown below:
= (Fixed Indirect materials + Indirect labor + factory supplies) ÷ expected activity level
= ($140,000 + $200,000 + $20,000) ÷ (1,00,000 machine hours)
= ($360,000) ÷ (1,00,000 machine hours)
= $3.6
For 80,000 machine hours, the variable cost would be
= 80,000 machine hours × $3.6
= $288,000
Now the total manufacturing overhead costs would equal to
= Fixed manufacturing overhead cost + variable manufacturing overhead cost
= $120,000 + $288,000
= $408,000
