Explanation:
The operating income of any entity can be calculated using the following formula:
Operating income=Net income+ income tax expense+ finance cost- other revenues
Net income in this question=$42,000
Income taxes=$18,000
finance cost=0
Other revenues=$5000
Operating income=$42,000+$18,000+0-$5000=$55,000
The operating income of any entity can also be calculated using the following formula:
Operating income=Revenues-operating costs
                              =$100,000-$45,000=$55,000
