Answer:
The fixed maintenance cost is $725,000 per month.
Step-by-step explanation:
The calculation of the fixed maintenance cost and the variable maintenance cost per hour by using high low method is presented below:
Variable maintenance cost per hour = (High Maintenance cost - low Maintenance cost) ÷ (High Maintenance hours - low Maintenance hours)
= ($1,247,000 - $1,175,000) ÷ (29,000 hours - 25,000 hours)
= $72,000 ÷ 4,000 hours
= $18
And the fixed cost equal to
= High Maintenance cost - (High Maintenance hours × Variable cost per hour)
= $1,247,000 - (29,000 hours × $18)
= $1,247,000 - $522,000
= $725,000
