Problem 21-7A (Continued)
Part 2 BREAK–EVEN ANALYSIS ASSUMING USE OF NEW MATERIALS
Step 1: Compute break-even in composite units—Use equation in Exhibit 21.29
Break-even in composite units = Fixed costs/Contribution margin per composite unit
= 1,364 composite units (rounded to the next whole unit)
*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
4 units of White
Variable cost of a composite unit………………………
Thus:
Step 2: Compute break-even in individual product unit sales
Unit sales of Red at break-even: 1,364 x 5 = 6,820 units
Step 3: Compute break-even in individual product dollar sales
Dollar sales of Red at break-even: 6,820 units x $20 = $136,400
Crossfoot Step 3 total with that from formula ($139 rounding difference):
Break-even in dollar sales = Fixed costs / Contribution margin ratio
Part 3
When a business invests in fixed assets, as in this case, there is an
