I am all the way to g but I'm so confused, no matter how I calculate it I just keep getting answers that the program says wrong. But I literally follows what the books says to calculate it...... Question G is making me frustrated.

g. Compute the rate of return on common stockholders' equity of 2018 and 2017. (Round your answers to one tenth of a percent, X.X%.)

Rate of return on common stockholders' equity = (Net income - Preferred dividends) / Average common stockholder's equity
