Step 1.
Company A
Contribution Margin Income Statement
Sales (given).............................................................................
$6,000,000
Step 2.
Company B
Contribution Margin Income Statement
Sales (given).............................................................................
$4,500,000
Step 3.
Interpretation: Company A benefits more from a 20% increase in sales.
This is because we expect a 20% increase in sales to yield a 72%

Exercise 21-25 (10 minutes)
1. Degree of operating leverage = Total contribution margin
Pretax income
2. If sales decrease by 5%, then pretax income will decrease by 4.0 x 5%,
3. If sales decrease by 5%, a total of 9,120 (computed as 9,600 x 95%)
units will be sold.
Contribution margin income statement, assuming 5% sales decrease:
