The breakdown of these costs at the 35,000 machine-hour level of activity is Utilities (variable) Supervisory salaries (fixed) Maintenance (mixed) Total overhead cost $ 49,000 68,000 55,050 $172,050

Solution

1) Calculate maintenance cost of july :

Maintenance cost of july = $87750

B) Variable cost per machine hour = (87750-55050)/(65000-35000) = 1.09 per machine hour

Fixed cost = 87750-(65000*1.09) = $16900

Y = a+bx

Y = 16900+1.09X

c) Total overhead cost formula :

Y = a+bx

Y = 84900+2.49X

d) Total overhead cost = (40000*2.49)+84900 = $184500
