Answer:
a) $7.50
Explanation:
The computation of the contribution margin per unit is shown below
The contribution margin per unit is
= Selling price per unit - variable cost per unit
= $23.75 per unit - $16.25 per unit
= $7.50 per unit
By substracting the variable cost per unit from the selling price per unit we can get the contribution margin per unit
Hence, the option a is correct
