Answer:
Operating loss will decrease by $20,000
Step-by-step explanation:
Operating loss from normal business activities and if the division is not shut down = $150,000.
Operating loss if division is shut down by the management = $130,000 ($480,000 - $350,000) because the management has determined that $350,000 of the $480,000 Fixed Costs shown would be eliminated if that happens.
So, if the Northern Division is shutdown, the Operating loss will decrease by $20,000 (From $150,000 to $130,000)
