Answer:
The weighted-average unit contribution margin is $33.49 per unit
Step-by-step explanation:
We know that,
Weighted average Contribution margin per unit = (Selling price per unit - Variable expense per unit) × sales mix
For A12 = ($55 - $40) × 55% = $8.25
For B22 = ($107- $79) × 29% = $8.12
For C124 = ($414 - $307) × 16% = $17.12
So, the total would be equal to
= $8.25 + $8.12 + $17.12
= $33.49 per unit
