Firm A and Firm B have debt-total assets ratios of 65 percent and 45 percent, respectively, and returns on total assets of 5% and 7%, respectively. Which firm has a greater return on equity

Answers

Answer:

Firm A

Step-by-step explanation:

D = Debt

A= Asset

E = Equity

ROA = Return on assets

ROE = Return on equity

For Firm A:

$(D)/(A)=0.65\n(E)/(A)=1-0.65=0.35\nROA = 0.05\nROE=(ROE)/((E)/(A))=(0.05)/(0.35) \nROE=0.1429=14.29\%$

For Firm B:

$(D)/(A)=0.45\n(E)/(A)=1-0.45=0.55\nROA = 0.07\nROE=(ROE)/((E)/(A))=(0.07)/(0.55) \nROE=0.1273=12.73\%$

Therefore, Firm A has a greater return on equity.
