Answer:
A. The profit margin on sales=15.48%
B. The return on assets=8.125%
C. The return on equity=11.93%
Explanation:
A.
Step 1: Determine the profit margin
The formula for calculating the profit margin can be expressed as;
P.M=(N.I/N.S)×100
where;
P.M=profit margin
N.I=net income
N.S=net sales
In our case;
P.M=unknown, to be determined
N.I=$65,000
N.S=$420,000
Substituting;
P.M=(65,000/420,000)×100=15.48%
The profit margin on sales=15.48%
B.
Step 2: Determine the return on assets
The formula for calculating the return on assets can be expressed as;
R.O.A=(N.I/A.T.A)×100
where;
R.O.A=return on assets
N.I=net income
A.T.A=average total assets
In our case;
R.O.A=unknown
N.I=$65,000
A.T.A=$800,000
Substituting;
R.O.A=(65,000/800,000)×100
R.O.A=0.08125×100=8.125%
C.
Step 3: Determine the return on equity
The formula for calculating the return on equity can be expressed as;
ROE=(N.I/A.T.E)×100
where;
ROE=return on equity
N.I=net income
A.T.E=average total equity
In our case;
ROE=unknown, to be determined
N.I=$65,000
A.T.E=(shareholder's equity at the beginning of the period+net income-dividends) and;
shareholder's equity at the beginning of the period=$500,000
net income=$65,000
dividends=$20,000
A.T.E=500,000+65,000-20,000=$545,000
Substituting;
ROE=(65,000/545,000)×100
ROE=11.93%
