Giving the following information:

Cost Machine Hours

January $52,200 20,000

February 75,000 29,000

March 57,000 22,000

April 64,000 24,500

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

Variable cost per unit= (75,000 - 52,200) / (29,000 - 20,000)= 2.53

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

Fixed costs= 75,000 - (2.53*29,000)= 1600

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

Fixed costs= 52,200 - (2.53*20,000)= 1600
