Explanation:
The computation of contribution margin per unit is shown below:-
For computing the contribution margin per unit first we need to find out the selling commission which is shown below:-
Selling commission = Sold product × Selling commission percentage
= $40 × 15%
= $6
Now, Contribution margin = Sales - Variable costs
=$40 - ($18 + $6)
= $40 - $24
=$16
