Answer:
y = $720 + $0.72 per MH
Step-by-step explanation:
The cost formula for the utility cost is shown below:
But before that following calculations need to be done
Variable cost per machine hour is
= [Total cost at highest level - Total cost at the lowest level] ÷ (Highest level-Lowest level)
= (2088 - 1620) ÷ (1900 - 1250)
= $0.72 per machine hour
Now
Total fixed cost is
= 2088 - (0.72 × 1900)
= $720
So, the Cost formula is
y = $720 + $0.72 per MH
