Answer:
The weighted-average unit contribution margin is $610
Explanation:
Hi, first we need to find the contribution margin for each line of product. This is as follows.
Laptops
[tex]Price-Var.Cost= Contrib.Margin[/tex]
[tex]700-300=400[/tex]
Desktops
[tex]1,800-700=1,100[/tex]
Now, the weighted-average unit contribution margin is as follows.
[tex]Contrib.Margin(Laptops)*Percent(Laptops)+Contrib.Margin(DeskT)*Percent(DeskT)[/tex]
[tex]1,100*0.3+400*0.7=610[/tex]
So, the weighted-average unit contribution margin for this company is $610
Best of luck
