Answer:
A. $ 450 comma 000
Step-by-step explanation:
In order to compute the fixed cost per month first we have to determine the variable cost per unit which is shown below.
Variable cost per hour = (High total cost - low total cost) ÷ (High production volume - low production volume)
= ($710,000 - $550,000) ÷ (13,000 units - 5,000 units )
= $160,000 ÷ 8,000 units
= $20
Now the fixed cost equal to
= High total cost - (High production volume × Variable cost per unit)
= $710,000 - (13,000 units × $20)
= $710,000 - $260,000
= $450,000
We simply applied the above formula
