Answer:
a. $550,000
Step-by-step explanation:
The total maintenance cost at 22,000 machine hours is given as:
Total maintenance costs=22,000*33.40=$734,800
The total maintenance cost at 25,000 machine hours is given as:
Total maintenance costs=25,000*30.40=$760,000
Variable cost per unit=760,000-734,800/25,000-22,000
=$8.4 per unit
Total costs=fixed costs+variable cost
734,800=fixed costs+8.4*22,000
Fixed cost=734,800-184,800=$550,000
So the answer is a. $550,000
