Answer:
The correct answer is D.
Step-by-step explanation:
Giving the following information:
Units sold 400
Selling price $ 100
Direct materials 30
Direct labor 20
Variable manufacturing overhead 10
To calculate the total contribution margin, first, we need to calculate the unitary contribution margin:
Unitary contribution margin= selling price - unitary variable cost
UCM= 100 - 30 - 20 - 10= 40
Total CM= 400*40= $40,000
