Answer:
$169 per unit
Explanation:
The computation of the contribution margin per unit is shown below:
Contribution margin per unit = Selling price per unit - Variable expense per unit
where,
Variable expense per unit = Direct materials per unit + Direct labor per unit + Variable manufacturing overhead per unit + Variable selling expense per unit
= $38 + $1 + $8 + $4
= $51
And, the Selling price per unit is $220
Now put these values to the above formula
So, the contribution margin would equal to
= $220 - $51
= $169 per unit
