a. margin of safetyb. indifference pointc. percentage change in profitsd. unit contribution margine. degree of operating leverage

The degree of operating leverage can be measured for a given level of sales by taking the ratio of contribution margin to operating income.

The correct answer is D

Explanation:

The degree of operating leverage is the ratio of contribution to operating income. It is calculated as:

Degree of operating leverage = Contribution/Operating income

Where contribution = Sales - Variable cost

start by isolating the variable on one side by adding 43w^2 to both sides.   the equation will read:

25w^2+5=0

*subtract 5 from both sides*

25w^2=-5

*divide both sides by 25*

w^2=-1/5

*take the square root of both sides*

w=√(-1/5)

the square root of -1 is i.   the square root of 5 remains √5

the answer is i/√5.
