Chapter 21 - Cost-Volume-Profit Analysis
Problem 21-7A (50 minutes)
Part 1 BREAK-EVEN ANALYSIS ASSUMING USE OF SAME MATERIALS
Step 1: Compute break-even in composite units—Use equation in Exhibit 21.29
*To compute the contribution margin per composite unit
Unit Sales Price Unit Variable Costs
5 units of Red
@ $20 per unit...................................................
@ $12 per unit...................................................
$100
$ 60
4 units of White
Thus:
Contribution margin per composite unit = $370 - $248 = $122
Contribution margin ratio (rounded) = $122 / $370 = 32.97%
Step 2: Compute break-even in individual product unit sales
Step 3: Compute break-even in individual product dollar sales
Dollar sales of Red at break-even: 10,250 units x $20 = $205,000
Dollar sales of White at break-even: 8,200 units x $35 = $287,000
Dollar sales of Blue at break-even: 4,100 units x $65 = $266,500
Crossfoot Step 3 total with that from formula ($235 rounding difference):

Part 2 BREAK-EVEN ANALYSIS ASSUMING USE OF NEW MATERIALS
Step 1: Compute break-even in composite units—Use equation in Exhibit 21.29
*To compute the contribution margin per composite unit
Unit Sales Price Unit Variable Costs
5 units of Red
@ $20 per unit......................................................
@ ($12 - $6) per unit............................................
$100
$ 30
Step 2: Compute break-even in individual product unit sales
Unit sales of Red at break-even: 1,364 x 5 = 6,820 units
Unit sales of White at break-even: 1,364 x 4 = 5,456 units
Unit sales of Blue at break-even: 1,364 x 2 = 2,728 units
Step 3: Compute break-even in individual product dollar sales
Crossfoot Step 3 total with that from formula ($139 rounding difference):
Break-even in dollar sales = Fixed costs / Contribution margin ratio
= ($250,000 + $50,000) / 59.46% = $504,541 (rounded)
Compare with Step 3 total = $504,680 ($136,400 + $190,960 + $177,320)

The contribution margin per unit is $14.625, and the contribution margin ratio is
81.25%.
Part 3 Analysis Component
Contribution margin shows how much of total sales are available to cover
fixed costs and contribute to operating income. This is why the title for this

Parts 1 and 2
The scatter diagram and its estimated line of cost behavior appear below.
Sales and cost amounts are in thousands of dollars.
Part 2 Calculation of variable and fixed costs
Part 3
The estimates in Part 2 can be used to predict the total costs that will be
incurred at sales levels of $100 and $170 (both in thousands).

Problem 21-3B (40 minutes)
Part 1
(a) Instructor note: Use the equation in Exhibit 21.11
Break-even in unit sales = Fixed costs / Contribution margin per unit
= $42,000 / $140*
= 300 units
*Contribution margin = $350 – $210 = $140
(b) Instructor note: Use the equation in Exhibit 21.12

Problem 21-4B (75 minutes)
Part 1 Instructor note: Use the equation in Exhibit 21.12
2015 break-even in dollar sales = Fixed costs / Contribution margin ratio
= $200,000 / 20%*
= $1,000,000

Part 2 Instructor note: Use equation in Exhibit 21.12 with predicted numbers
2016 break-even in dollar sales = Fixed costs / Contribution margin ratio
= $350,000* / 60%**
= $583,333 (rounded to whole dollars)

Unit sales price and variable costs are computed in Part 1 and used in these computations:
* Product BB sales = 33,000 units x $16; Product TT sales = 33,000 units x $16.
**Product BB variable costs = 33,000 units x $11.20;
Product TT variable costs = 33,000 units x $2.

If sales were to greatly increase, Product TT would experience the greater
increase in income because it would gain more contribution margin per

Factors that could cause Product BB to have lower fixed costs include:
Labor arrangement that pays workers for units produced.
Sales representatives that work totally on commission.
