Exercise 18-25 (10 minutes)
1. Degree of operating leverage = Total contribution margin
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:

Unit sales price and variable costs are computed in Part 1 and used in these computations:
* Product T sales = 60,000 units x $40; Product O sales = 60,000 units x $40.
** Product T variable costs = 60,000 units x $32; Product O variable costs = 60,000 units x $5.
Part 4
If sales were to greatly decrease, Product O would suffer the greater loss
because it would lose more contribution margin per unit than Product T
($35 for O versus $8 for T). Examining the operating leverage of these two
products can yield the same inference. Specifically, higher operating
leverage reflects higher fixed costs, which implies greater impacts on
income from changes in sales levels. In the extreme, at zero sales, Product
