Sales in North Corporation increased from $80,000 per year to $84,000 per year while

4 times

Explanation:

Given that,

Initial sales = $80,000

New sales = $84,000

Initial net operating income = $30,000

New net operating income = $36,000

The degree of operating leverage is determined by dividing the percentage change in net operating income by the percentage change in the sales.

Percentage change in net operating income:

= [(New net operating income - Initial net operating income) ÷ Initial net operating income] × 100

= [($36,000 - $30,000) ÷ $30,000] × 100

= ($6,000 ÷ $30,000) × 100

= 0.2 × 100

= 20%

Percentage change in sales:

= [(New sales - Initial sales) ÷ Initial sales] × 100

= [($84,000 - $80,000) ÷ $80,000] × 100

= ($4,000 ÷ $80,000) × 100

= 0.05 × 100

= 5%

Degree of operating leverage:

= Percentage change in net operating income ÷ Percentage change in sales

= 20 ÷ 5

= 4 times
