Answer:
The weighted-average unit contribution margin for Concord is $70.50
Explanation:
For computing the weighted-average unit contribution margin , first we have to compute the contribution margin which is shown below:
Contribution margin per unit = Selling price per unit - Variable expense per unit
For Q- drive, it will be
= $90 - $30
= $60 per unit
And, for Q-drive plus,
= $135 - $60
= $75 per unit
Now the weighted-average unit contribution margin equal to
= Weighted sales mix × contribution margin + Weighted sales mix × contribution margin
= 30% ×$60 + 70% × $75
= $18 + $52.50
=$70.50 per unit
