Estimate both the variable costs per unit and the total monthly fixed costs using the high-low method. (Do not round Intermediate calculations.) High-Low method-Calculation of variable cost per unit Total cost at the high point Variable costs at the high point: Volume at the high point Variable cost per unit Total variable costs at the high point Total fixed costs Total cost at the low point Variable costs at the low point Volume at the low point Variable cost per unit Total variable costs at the low point High-Low method - Calculation of fixed costs
