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 Month Units Sold Total Cost 315,500 $153,000 7 364,500 $311,084 2 160,500 96,750 B 265,500 147,250 3 260, 500 201,100 9 76,900 69,500 4 200, 500 95,500 10 145,500 126,125 5 285,500 197,000 11 89,500 89,500 185,500 107,500 12 95,500 86,150 6 1. Estimate both the variable costs per unit and the total monthly fixed costs using the high-low method. (Do not ound intermediate calculations.) Variable cost per unit = $ Change in cost Change in volume High-Low method - Calculation of Variable Cost per unit $ Cost at high point minus cost at low point 287.600 Volume at high point minus volume at low point 241,584 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 $ 1.19 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
