Answer:
(a) Determination of variable electricity cost per machine hour is as follows:
Variable cost = (Electricity costs for the highest machine hours used - Electricity costs for lower machine hours used) / (Highest machine-hours - Lowest machine hours)
= ($8,897 - $7,301) / (22,400 - 18,200)
= $1,596 / 4,200
= $0.38 per machine hour
Therefore, the variable electricity cost per machine hour is $0.38
(b) Determination of monthly fixed electricity costs in total is as follows:
Fixed electricity costs = Total electricity cost for 22,400 machine hours - ( Machine hours x variable electricity cost)
= $8,897 - (22,400 x $0.38)
= $385
Therefore, the monthly fixed electricity costs in total is $385.
(c) Estimation of total electricity costs for 24,000 machine hours is as follows:
Total electricity costs = $385 + (24,000 machine hours x $0.38)
= $9,505
Therefore, total electricity costs for 24,000 machine hours is $9,505.
