Pretax income ………………………………………………………………..
$1,125,000 / $750,000
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%

Part 1 BREAKEVEN ANALYSIS ASSUMING USE OF SAME MATERIALS
Step 1: Compute break-even in composite unitsUse equation in Exhibit 18.29
*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
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
Crossfoot Step 3 total with that from formula ($235 rounding difference):

Unit Sales Price
Unit Variable Costs
4 units of White
5 units of Red
Selling price of a composite unit ……………………..
Variable cost of a composite unit …………………….
$370
$150
Thus:
Contribution margin per composite unit = $370 – $150 = $220
Contribution margin ratio (rounded) = $220/ $370 = 59.46%
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: 6,820 units x $20 = $136,400
