Cant figure out Z for either capital gains or dividend yeild

Consider four different stocks, all of which have a required return of 20 percent and a most recent dividend of $3.70 per share. Stocks W X, and Y are expected to maintain constant growth rates in dividends for the foreseeable future of 10 percent, O percent, and -5 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 14 percent growth rate thereafter. What is the dividend yield and capital gains yield for each of these four stocks? (Leave no cells blank - be certain to enter "O" wherever required. A negative answer should be indicated by a minus sign. Do not round intermediate calculations and enter your answers as a percent rounded to 1 decimal place, e.g., 32.1.)
