Answer:
The correct answer is: option D
Explanation:
The degree of operating leverage (DOL) is a measure used to evaluate how a company's operating income changes after a percentage change in its sales. A company's operating leverage involves fixed costs and variable costs. It is a financial ratio that measures the sensitivity of a company’s operating income to its sales. This financial metric shows how a change in the company’s sales will affect its operating income.
There are two main formulas to calculate the DOL:
DOL= Contribution Margin/ Operating Income
or
DOL= [Qx(P-V)] / [QX(P-V)-F)
Where:
Q: the number of units
P: the price per unit
V: the variable cost per unit
F: the fixed costs
