Answer:
The correct option is A
Step-by-step explanation:
Contribution Margin = Sales - Variable expense
= $150,000 - $120,000
= $30,000
Doombug's Profit Margin = Avoidable fixed expenses - Contribution Margin
= $8,000 - $30,000
= ($22,000)
Increase or Decrease in net operating income = Additional contribution margin - Doombug's Profit Margin
= $16,000 - ($22,000)
= ($6,000)
Therefore, there is decrease in net operating income of Doombug. So, there is decrease of $6,000.
