Maintenance Costs Machine Hours

January $2,860 320

February 3,160 370

March 3,760 520

April 4,660 670

May 3,360 520

June 5,260 720

To calculate the variable and fixed costs, we need to use the following formulas:

Variable cost per unit= (Highest activity cost - Lowest activity cost)/ (Highest activity units - Lowest activity units)

Variable cost per unit= (5,260 - 2,860) / (720 - 320)

Variable cost per unit= $6

Fixed costs= Highest activity cost - (Variable cost per unit * HAU)

Fixed costs= 5,260 - (6*720)

Fixed costs= $940

Fixed costs= LAC - (Variable cost per unit* LAU)

Fixed costs= 2,860 - (6*320)

Fixed costs= $940
