Answer:
Contribution margin= 144,000
Step-by-step explanation:
Giving the following information:
Total Sales $ 400,000
Variable expenses 280,000
Contribution margin 120,000
To calculate the new contribution margin, we need to increase sales and variable cost by 20%
Total sales= 400,000*1.20= 480,000
Variable expense= 280,000*1.2= (336,000)
Contribution margin= 144,000
