Answer:
A. 0.21
B. $378
Step-by-step explanation:
1. Calculation for the company's contribution margin (CM) ratio
Fist step is to calculate the CM
CM = 308,000 - $243,320
CM= 67,320
Now let calculate the CM Ratio
Using this formula
CM / Sales = CM Ratio
Let plug in the formula
CM Ratio = 64,680 / 308,000
CM Ratio = 0.21
Therefore the company's contribution margin (CM) ratio is 0.21
2. Calculation for the estimated change in the company's net operating income if it can increase total sales by $1,800
Estimated change in the company's net operating income=CM Ratio x 1,800
Estimated change in the company's net operating income= 0.21*$1,800
Estimated change in the company's net operating income=$378
Therefore the estimated change in the company's net operating income if it can increase total sales by $1,800 is $378
