Answer:
The variable maintenance cost per unit would be $8.33 and the total fixed maintenance cost would be $267
Step-by-step explanation:
The computation of the fixed cost and the variable cost per hour by using high low method is shown below:
Variable maintenance cost per unit = (High maintenance cost - low maintenance cost) ÷ (High level of activity - low level of activity)
= ($1,100 - $600) ÷ (100 direct hours - 40 direct hours)
= $500 ÷ 60 direct hours
= $8.33
Now the fixed cost equal to
= High maintenance cost - (High level of activity × Variable maintenance cost per unit )
= $1,100 - (100 direct hours × $8.33)
= $1,100 - $833.33
= $267
