Final answer:
Without specific financial data, an exact contribution margin for the strip line cannot be calculated if the parquet product line is dropped. The contribution margin is the sales revenue from the strip line minus its variable costs. Fixed costs are not included unless they are eliminated by dropping the parquet line.
Step-by-step explanation:
To determine the contribution margin for the strip line if the parquet product line is dropped, you would need detailed financial information about both product lines. The contribution margin is calculated as total sales revenue minus variable costs of production for the given product line. If specific numbers were provided, you could calculate the contribution margin for the strip line by subtracting the variable costs associated with producing the strip line from the sales revenue generated by the strip line. It's important to note that fixed costs do not change with the production volume and would not be considered unless they are directly attributable to the strip line and would be eliminated if the parquet line is dropped.
However, since no specific financial data is provided in the question, we cannot calculate an exact figure. The principle remains that the contribution margin would reflect the remaining sales revenue from the strip line after variable costs are deducted.
