Final answer:
The degree of operating leverage (DOL) is 0.
Step-by-step explanation:
The degree of operating leverage (DOL) measures the percentage change in operating income resulting from a change in sales volume. It can be calculated by dividing the percentage change in operating income by the percentage change in sales. Under the scenario where the total variable expenses are $21,840 and the total fixed expenses are $52,000, we need to calculate the new contribution margin (CM) and operating income before calculating the DOL.
To calculate the new CM, subtract the reversed total variable expenses from the sales (80,000 - 21,840 = $58,160). To calculate the new operating income (NOI), subtract the reversed total fixed expenses from the new CM (58,160 - 52,000 = $6,160).
Now we can calculate the DOL:
DOL = (New NOI - Old NOI) / (Old NOI)
Substituting the values:
DOL = (6,160 - 6,160) / 6,160
DOL = 0
