Required information [The following information applies to the questions displayed below.] Alden Co.'s monthly unit sales and total cost data for its operating activities of the past year follow. Management wants to use these data to predict future fixed and variable costs. Month Units Sold Total Cost 1 320,000 $160,000 Month 7 Units Sold 340,000 Total Cost $220,000 2 160,000 100,000 B 280,000 3 280,000 220,000 9 80,000 4 200,000 100,000 10 160,000 160,000 64,000 140,000 5 6 300,000 200,000 230,000 11 100,000 120,000 12 110,000 100,000 80,000 1. Estimate both the variable costs per unit and the total monthly fixed costs using the high-low method. (Do not round intermediate calculations.) 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 Total fixed costs High-Low method - Calculation of variable cost per unit High-Low method - Calculation of fixed costs 0
