Final answer:
If the parquet product line is dropped, the contribution margin for the strip line would be $157,500 and the contribution margin for the plank line would be $76,000. The more cost-effective alternative is to keep the parquet product line, with a cost effectiveness of $5,000.
Step-by-step explanation:
To determine the contribution margins for the strip line and the plank line if the parquet product line is dropped, we need to consider the effects of dropping the parquet line on the sales of the strip line and the plank line.
Given that dropping the parquet product line would reduce sales of the strip line by 10% and sales of the plank line by 5%, we can calculate the contribution margins as follows:
- Contribution margin for the strip line = (Contribution margin without drop) - (Contribution margin without drop * reduction in sales of strip line)
= $175,000 - ($175,000 * 0.10)
= $175,000 - $17,500
= $157,500 - Contribution margin for the plank line = (Contribution margin without drop) - (Contribution margin without drop * reduction in sales of plank line)
= $80,000 - ($80,000 * 0.05)
= $80,000 - $4,000
= $76,000
Therefore, the contribution margin for the strip line would be $157,500 and the contribution margin for the plank line would be $76,000 if the parquet product line is dropped.
Based on the information provided, the more cost-effective alternative would be to keep the parquet product line.
To calculate the cost effectiveness, we need to compare the segment margin with and without the parquet product line. The segment margin with the parquet product line is $115,000 and without the parquet product line is $120,000. Therefore, the cost effectiveness of keeping the parquet product line is $120,000 - $115,000 = $5,000.
