Answer:
The elimination of the North division would result in an increase to net operating income of $100,000 for the South division.
Step-by-step explanation:
Please see computation of the company's overall net profit
= South sales - South variable costs - South traceable fixed costs - South allocated common corporate cost - North allocated common corporate cost
= $880,000 - $550,000 - $80,000 - $50,000 - $100,000
= $100,000 profit.
N.B
Since the North division has been eliminated, all the items for North division would all be ignored except its allocated common corporate cost.
