BLOOM’ S TAXONOMY TABLE
ANSWERS TO QUESTIONS
1. (a) Cost behavior analysis is the study of how specific costs respond to changes in the level of activity
within a company.
(b) Cost behavior analysis is important to management in planning business operations and in deciding
between alternative courses of action.
3. Fixed costs remain the same in total regardless of changes in the activity level. In contrast, fixed
costs per unit vary inversely with activity. As volume increases, fixed costs per unit decline and vice
versa.
4. (a) The relevant range is the range of activity over which a company expects to operate during
the year.
5. This is true. Most companies operate within the relevant range. Within this range, it is possible to
establish a linear (straight-line) relationship for both variable and fixed costs. If a relevant range
cannot be established, segregation of costs into fixed and variable becomes extremely difficult.
6. Apartment rent is fixed because the cost per month remains the same regardless of how much Adam
7. For CVP analysis, mixed costs must be classified into their fixed and variable elements. One approach
to the classification of mixed costs is the high-low method.
8. Variable cost per unit is $1.30, or [($165,000 – $100,000) ÷ (90,000 – 40,000)]. At any level of activity,
fixed costs are $48,000 per month [$165,000 – (90,000 X $1.30)].
Questions Chapter 22 (Continued)
12. Disagree. Knowledge of the break-even point is useful to management in deciding whether to introduce
new product lines, change sales prices on established products, and enter new market areas.
13. $26,000 ÷ 25% = $104,000
15. Margin of safety is the difference between actual or expected sales and sales at the break-even
point. 1,250 X $12 = $15,000; $15,000 – $13,200 = $1,800; $1,800 ÷ $15,000 = 12%.
16. At break-even sales, the contribution margin is equal to the fixed costs. The contribution margin
ratio is:

*18. Under absorption costing, both variable and fixed manufacturing costs are considered to be
product costs. Under variable costing, only variable manufacturing costs are product costs and
fixed manufacturing costs are expensed when incurred.
*19. (a) The rationale for variable costing centers on the purpose of fixed manufacturing costs, which
is to have productive facilities available for use. Since these costs are incurred whether a
SOLUTIONS TO BRIEF EXERCISES
BRIEF EXERCISE 22-1
Indirect labor is a variable cost because it increases in total directly and
proportionately with the change in the activity level.
Supervisory salaries is a fixed cost because it remains the same in total regard-
less of changes in the activity level.
Maintenance is a mixed cost because it increases in total but not proportionately
with changes in the activity level.

Re: Assumptions underlying CVP analysis
CVP analysis is a useful tool in analyzing the effects of changes in costs
and volume on a company’s profits. However, there are some assumptions
which underlie CVP analysis. When these assumptions are not valid,
the results of CVP analysis may be inaccurate.
The five assumptions are:
1. The behavior of both costs and revenues is linear throughout
the relevant range of the activity index.
