c$.$ Norman Osborn changed his mind about perpetual dividend payment system. Instead, he wants to implement a plan which includes $15$ years of dividend payments growing at a $5\%$ rate and afterwards he would like to decrease the dividends by $2\%$ for forever. Norman will begin his plan a year from now and Oscorp just paid a dividend of $$4\mathrm{.}50.$ If the cost of equity is still $13\%,$ how much would one share of Oscorp be worth should he aim to successfully implement this dividend policy change?
