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 Month Units Sold 323,000 168,000 268,000 208,000 293,000 193,000 Total Cost $160,500 104,250 208,600 103,000 204,500 115,000 Units Sold 357,000 273,000 75,400 153,000 97,000 103,000 Total Cost $256,304 154,750 62,000 133,625 97,000 78,650 2. Estimate both the variable costs per unit and the total monthly fixed costs using the high-low method. (Do not round intermediate calculations.) X Answer is not complete. High-Low method - Calculation of Variable Cost per unit Change in cost Cost at high point minus cost at low point Change in volume Volume at high point minus volume at low point High-Low method - Calculation of Fixed Costs 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
