Answer:
$29.50
Step-by-step explanation:
The computation of the contribution margin per unit is shown below:
Contribution margin per unit = Selling price per unit - Variable cost per unit
where,
Selling price per unit is $50
And, the variable cost per unit = $24 - $3.5 = $20.5
Now put these values to the above formula
So, the value would equal to
= $50 - $20.5
= $29.50 per unit
