thus,

Power's profit margin will be - $ 80,000 if the Windsor division was dropped.

The contribution margin of the West business segment is $430,000

The contribution margin is the difference between the sales revenue and the variable expense. Other cost like - fixed expense, traceable fixed cost is irrelevant while calculating the fixed cost.

So,

Contribution margin for the West business :

= $430,000

Thus, the contribution margin of the West business segment is $430,000
