Answer:
b. $311,600
Explanation:
For the computation of total contribution margin first we need to find out the contribution margin per unit which is shown below:-
Contribution Margin per Unit = Contribution Margin ÷ Units Sold
= 319,200 ÷ 8,400
= $38
Total Contribution Margin = Contribution Margin per Unit × Units Sold
= $38 × 8,200
= $311,600
Therefore for computing the total contribution margin we simply applied the above formula.
