Consider four different stocks, all of which have a required return of $12$ percent and a most recent dividend of $$3\mathrm{.}90$ per share. Stocks $W,x,$ and $Y$ are expected to maintain constant growth rates in dividends for the foreseeable future of $10$ percent, $0$ percent, and $-4$ percent per year, respectively. Stock $Z$ is a growth stock that will increase its dividend by $20$ percent for the next two years and then maintain a constant $10$ percent growth rate thereafter.

What is the dividend yield for each of these four stocks? $($Do not round intermediote calculations and enter your answers as a percent rounded to $2$ decimal places, e$.$g$.,32\mathrm{.}16.)$

Answer is complete but not entirely correct.
