Total Lumber Units Produced Total Total Machine Utilities Depreciation Cost Cost Cost 6,000 shelves $60,000 $7,900 $140,000 12,000 shelves 120,000 14,800 140,000 24,000 shelves 240,000 28,600 140,000 30,000 shelves 300,000 35,500 140,000 1. Determine whether the costs in the table are variable, fixed, mixed, or none of these. Lumber Variable Cost Utilities Mixed Cost Depreciation Fixed Cost 2. For each cost, determine the fixed portion of the cost, and the per-unit variable cost. If there is no amount or an amount is zero, enter "0". Recall that, for N = Number of Units Produced, Total Costs = (Variable Cost Per Unit x N) + Fixed Cost. Complete the following table with your answers. Round variable portion of cost (per unit) answers to two decimal places. 2. For each cost, determine the fixed portion of the cost, and the per-unit variable cost. If there is no amount or an amount is zero, enter "0". Recall that, for N = Number of Units Produced, Total Costs = (Variable Cost Per Unit x N) + Fixed Cost. Complete the following table with your answers. Round variable portion of cost (per unit) answers to two decimal places. Fixed Portion of Cost Variable Portion of Cost (per Unit) Cost Lumber 0 10 Utilities 1,000 1.15 Depreciation 140,000 0 High-Low Biblio Files Company is the chief competitor of Cover-to-Cover Company in the bookshelf business.

From the data previously provided, help Biblio Files Company estimate the fixed and variable portions of its total costs using the high-low method. Recall that Total Costs = (Variable Cost Per Unit x Number of Units Produced) + Fixed Cost. Complete the following table. Total Fixed Cost Variable Cost per Unit 2. With your Total Fixed Cost and Variable Cost per Unit from the high-low method, compute the total cost for the following values of N (Number of Units Produced). Number of Units Produced Total Cost 3,500 4,360 4,800 3. Why does the total cost computed for 4,360 units not match the data for January? a. The high-low method is accurate only for months in which production is at full capacity. b. The high-low method only gives accurate data when fixed costs are zero. C. The high-low method gives a formula for the estimated total cost and may not match levels of production other than the highest and lowest. d. The high-low method gives accurate data only for levels of production outside the relevant range.

Cover-to-Cover Company's contribution margin ratio is lower, meaning that it's more efficient in its operations. C. The companies have goals that are not in the relevant range. d. The answers are not different; each company has the same required sales amount for the coming year to achieve the desired target profit
