Answer:
c. difference between total variable costs and total costs at a particular activity level
Step-by-step explanation:
The high low method consists of calculating costs on the basis of highest & lowest activity & comparing their corresponding total costs.
Variable cost per unit is found by : change in cost divided by the change in activity level for two points
Variable Cost per unit = Highest activity cost - Lowest activity cost
Highest activity units - lowest activity units
Fixed Cost is thereafter calculated by subtracting Total Variable Costs from Total Cost
Fixed Cost = Highest Activity Total Cost - [ (Variable cost per unit) x (highest activity units)
Fixed Cost = Lowest Activity Cost - [ (Variable cost per unit) x (lowest activity units)]
