Required information [The following information applies to the questions displayed below.] 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 317, 090 $ 154, 500 162, 090 98, 250 262, 090 202, 600 202, 090 97, 000 287, 090 198, 500 187, 090 109, 090 363, 090 299,984 267, 090 148, 750 76, 600 68, 090 10 147, 090 127, 625 11 91, 090 91, 090 12 97, 090 84, 650 1. Estimate both the variable costs per unit and the total monthly fixed costs using the high-low method. Note: Do not round intermediate calculations.Total cost at the highest volume variable costs at highest volume: Highest volume 1rr'ariable cost per unit Total variable costs at highest volume Total xed costs Total cost at the lowest volume variable costs at lowest volume: Lowest volume 1variable cost per unit Total variable costs at lowest volume Total xed costs 2. Predict future total costs when sales volume is (a) 374,000 units and (b) 414,000 units. 374,000 units 414,000 units Total cost
