Structuring a Keep-or-Drop Product Line Problem with Complementary Effects Shown below is a segmented income statement for Hickory Company's three wooden flooring product lines: Hickory's management is deciding whether to keep or drop the parquet product line. Hickory's parquet flooring product line has a contribution margin of $50,000 (sales of $300,000 less total variable costs of $250,000). All variable costs are relevant. Relevant fixed costs associated with this line include 80% of parquet's machine rent and all of parquet's supervision salaries. In addition, assume that dropping the parquet product line would reduce sales of the strip line by 24% and sales of the plank line by 20%. All other information remains the same. Required: 1. If the parquet product line is dropped, what is the contribution margin for the strip line? $x For the plank line? $ 2. Which alternative (keep or drop the parquet product line) is now more cost effective and by how much? by $ x Structuring a Make-or-Buy Problem Fresh Foods, a large restaurant chain, needs to determine if it would be cheaper to produce 5,000 units of its main food ingredient for use in its restaurants or to purchase them from an outside supplier for $12 each. Cost information on internal production includes the following: Fixed overhead will continue whether the ingredient is produced internally or externally. No additional costs of purchasing will be incurred beyond the purchase price. If required, round your answers to the nearest whole number. Required: 1. What are the alternatives for Fresh Foods? 2. List the relevant cost(s) of internal production and of external purchase. 3. Which alternative is more cost effective and by how much? (Use total cost when giving your answer.) 4. Now assume that 20% of the fixed overhead can be avoided if the ingredient is purchased externally. Which alternative is more cost effective and by how much? (Use total cost when giving your answer.)
