Answer:
The correct answer is letter "A": two costs at the highest and lowest volumes.
Step-by-step explanation:
The high-low method is used in cost accounting at the moment of separating variable and fixed costs, moreover when the input is limited or lacks detail. With this approach, the highest and lowest activity levels are compared. Variable costs are calculated by dividing the highest activity cost by the highest activity units. Fixed costs are computed by subtracting the result of multiplying the variable costs from the highest activity units from the highest activity cost.
Therefore, the estimated line of cost behavior in this approach connects costs at the highest lowest production levels.
