Answer:
The weighted-average unit contribution margin is $7.40
Explanation:
The weighted average unit contribution margin is given by the below formula:
weighted-average unit contribution margin=Wa*Margin of A+Wb*Margin of B
Wa is the weight of product A=70% or 0.70
Margin of product A is $8.04
Wb is the weight of product B =30% or 0.30
Margin of product B is $5.92
weighted-average unit contribution margin=(0.70*$8.04)+(0.30*$5.92)
weighted-average unit contribution margin=$ 7.40
