Problem 18-7A (50 minutes)
Part 1 BREAK-EVEN ANALYSIS ASSUMING USE OF SAME MATERIALS
Step 1: Compute break-even in composite units—Use equation in Exhibit 18.29
Break-even in composite units = Fixed costs/Contribution margin per composite unit
= $250,000 / $122*
Problem 18-7A (Continued)
Part 2 BREAK-EVEN ANALYSIS ASSUMING USE OF NEW MATERIALS
Step 1: Compute break-even in composite units—Use equation in Exhibit 18.29
Break-even in composite units = Fixed costs/Contribution margin per composite unit
= ($250,000 + $50,000) / $220*

Unit sales price and variable costs are computed in Part 1 and used in these computations:
* Product BB sales = 64,000 units x $16; Product TT sales = 64,000 units x $16.
**Product BB variable costs = 64,000 units x $11.20;
Product TT variable costs = 64,000 units x $2.
Part 4
If sales were to greatly increase, Product TT would experience the greater
increase in income because it would gain more contribution margin per
unit than Product BB ($14 for TT versus $4.80 for BB). Examining the
operating leverage of these two products would yield the same inference.
