High-Low and Cost Formula

Adams Company has accumulated the following total manufacturing overhead costs for two levels of activity (within the relevant range):

	Low	High
Activity (direct labor hours)	30,000	50,000
Total manufacturing overhead	$270,000	$362,000

The total overhead cost includes variable, fixed, and mixed costs. At 50,000 direct labor hours, the total cost breakdown is as follows:

Variable cost	$200,000
Fixed cost	90,000
Semi-mixed cost	$72,000
