Answer:
The answer is: The variable maintenance cost is $0.21 per machine hour
Step-by-step explanation:
To find the variable maintenance cost per machine hour we must divide the total amount spent in maintenance costs by the total amount of production hours.
Since both production hours and maintenance cost vary so much, we must high-low method:
variable maintenance cost = (highest maintenance cost - lowest maintenance cost) / (highest machine hours - lowest machine hours) =
= ($10,500 - $8,600) / (23,000 - 14,000) = $0.21 per machine hour
