Alden Company's monthly data for the past year follow. Management wants to use these data to predict future variable and fixed costs. Month Units Sold Total Cost Month Units Sold 1 320,000 $ 160,000 7 340,000 2 160,000 100,000 8 280,000 Total Cost $220,000 160,000 3 280,000 220,000 9 80,000 64,000 4 200,000 100,000 10 160,000 140,000 5 6 300,000 200,000 230,000 120,000 11 100,000 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 2. Predict future total costs when sales volume is (a) 220,000 units and (b) 240,000 units. Units Total $ FA Predictions (a) (b) 220,000 240,000 0 $ EA 0 0
