Answer:
The rate of return on common stockholders' equity is 27.80%.
Explanation:
Return on common shareholders equity
= net income of a company for the year/[ Common stockholders' equity at the beginning of the year + Common stockholders' equity was at the end of the year]
= $570,000/[$1,800,000 + $2,300,000]/2
= 27.80%
Therefore, the rate of return on common stockholders' equity is 27.80%.
