Answer:
a. Operating leverage = Contribution Margin / Income for operation
Beck Inc. = $111,800 / $43,000 = 2.6 times
Bryant Inc = $207,000 / $115,000 = 1.8 times
b. Increase on Income from operations for each company if the sales of each increased by 20%? will be:
Beck Inc = 2.6 * 10%
=0.52
=52%
Bryant Inc = 1.8 * 20
=0.36
=36%
