Answer:
a. $1,482,000
Step-by-step explanation:
The computation of the total manufacturing overhead cost is shown below;
But before that first we need to do following calculations
The Variable overhead for 50000 machine hours is
= $1,260,000 - $150,000
= $1,110,000
As depreciation is not variable cost so it would be excluded
Now for 60,000 machine hours, the variable overhead is
= ($1,110,000 ÷ 50,000) × 60,000
= $1,332,000
And, the fixed overhead is $150,000 i.e depreciation expense
So, the total manufacturing overhead cost is
= Fixed manufacturing overhead + variable manufacturing overhead
= $150,000 + $1,332,000
= $1,482,000
