Answer:
Step-by-step explanation:
Vanikoro Financials.
Post closure of Rubber division, vanikoro's financials will look like this:
Sales 500,000
Variable costs 210,000
Contribution Margin 290,000
Traceable fixed costs 130,000
Segment Margin 160,000
Corporate fixed costs 140,000
Net income $20,000.
Net income pre closure of Rubber division is $50,000
Therefore the net income of the group would have declined by $30,000
