Confirm your calculations in Requirement 3 above by increasing the unit sales in your worksheet by 20% so that the Data area looks like this:

Unit sales 60,000 units

Selling price per unit 50 per unit

Variable expenses per 30 per unit

Fixed expenses 500,000

(a) What is net operating income? (Negative amount should be indicated by a minus sign.)

(b) By what percentage did the net operating income increase?

a. $700,000

b. 40% increase

Explanation:

As per the data given in the question,

a)  

Increase in sales = 20%

So last  unit sale

= Unit sales ÷ increased unit sales percentage

= 60,000 ÷ 1.2

= 50,000

Previous year operating income  is

= Last unit sales × (Selling price per unit - variable cost per unit) - Fixed expenses

= 50,000 × ($50-$30) - $500,000

= $500,000

Current Net operating income  is

= Current units sales × (Selling price per unit - variable cost per unit) - Fixed expenses

= 60,000 × ($50-$30) - $500,000

= $700,000

b)

Percentage increase in net operating income is

= (Current Net operating income - Previous year operating income) ÷ Previous year operating income

= ($700,000 - $500,000) ÷ $500,000

= 40% increase

The net operating income is the income which is come after deducting all the variable cost, fixed cost from the sales revenue i.e earned by the company
