Problem 21-7B (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
*To compute the contribution margin per composite unit
Unit Sales Price Unit Variable Costs
6 units of Product 1
@ $40 per unit………………………………………………..
@ ($30 – $10) per unit……………………………………..
$240
$120
4 units of Product 2
Thus:
Step 2: Compute break-even in individual product unit sales
Unit sales of Product 1 at break-even: 1,429 x 6 = 8,574 units
Step 3: Compute break-even in individual product dollar sales
Dollar sales of Product 1 at break-even: 8,574 units x $40 = $342,960
Crossfoot Step 3 total with that from formula ($171 of rounding differences):
Break-even in $ sales = Fixed costs / Contribution margin ratio
Part 3
When a business invests in fixed assets, as in this case, there is an increase
in its risk level (more fixed costs must be recovered). However, investments
