Answer:
Variable cost per unit= $0.5 per inspection
Explanation:
Giving the following information:
The costs ranged from $4,400 for 1,400 inspections to $4,200 for 1,000 inspections.
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= (4,400 - 4,200) / (1,400 - 1,000)
Variable cost per unit= $0.5 per inspection
