Answer:
3
Explanation:
The computation of the degree of operating leverage is shown below:
= (Sales - Variable expense) ÷ (Sales - Variable expense - Fixed expense)
= ($700,000 - $490,000) ÷ ($700,000 - $490,000 - $140,000)
= $210,000 ÷ $70,000
= 3
The (Sales - Variable costs) = Contribution margin
The (Sales - Variable costs - Fixed costs) = EBIT i.e Earnings before interest and taxes
