The controller of Sunland Industries has collected the following monthly expense data for use in analyzing the cost behavior of maintenance costs. Month Total Maintenance Costs Total Machine Hours January $2,590 330 February 2,890 380 March 3,490 530 April 4,390 660 May 3,090 530 June 5,470 730 (a1) Determine the variable cost components using the high-low method. (Round answer to 2 decimal places e. g. 2.25.) Variable cost per machine hour $

Variable cost per unit= $7.2 per unit

Explanation:

Giving the following information:

Month Total Maintenance Costs Total Machine Hours

January: $2,590 - 330

February: $2,890 - 380

March: $3,490 - 530

April: $4,390 -  660

May: $3,090 - 530

June: $5,470 - 730

To calculate the variable cost under the high-low method, we need to use the following formula:

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

Variable cost per unit= (5,470 - 2,590) / (730 - 330)

Variable cost per unit= $7.2 per unit
