Final answer:
The contribution margin per unit is $107.30.
Step-by-step explanation:
The contribution margin per unit can be calculated by subtracting the variable cost per unit from the selling price per unit. In this case, the selling price is $290 per unit and the variable cost is $182.70 per unit. Subtracting the variable cost from the selling price, we get:
Contribution margin per unit = Selling price per unit - Variable cost per unit
Contribution margin per unit = $290 - $182.70
Contribution margin per unit = $107.30
