The degree of operatingleverage is calculated by the formular
(sales - variable cost) / (sales - fixed cost - variable cost).
In the given question,
sales = $2,000,000
variable cost = $1,100,000
fixed cost = $750,000
The degree of operating leverage is (2,000,000 - 1,100,000) / (2,000,000 - 750,000 - 1,100,000) = 900,000 / 150,000 = 6.
Therefore, the degree of operating leverage is 6.
