Answer:
Krell's dividend yield and equity cost of​ capital are 4.23% and 19.95%
Explanation:
Dividend yield = expected dividend/price today
             = $ 0.89/$ 21.05
             = 4.23%
Equity cost of capital = (Ending share price - Initial price + Dividend per share) / Initial price * 100
                  = [($24.36 - $21.05 + 0.89)/$21.05]*100
                  = 19.95%
Therefore, Krell's dividend yield and equity cost of​ capital are 4.23% and 19.95%
