A stock has a price $($i$.$e$.,$ present value of all cash flows from the stock expected by investors$)$ of $$27\mathrm{.}50$ today. It is expected to pay a dividend of $$1\mathrm{.}10$ per share next year, $$1\mathrm{.}20$ per share in the following year, $$1\mathrm{.}90$ in the subsequent U years $($i$.$e$.,$ pay a dividend of $$1\mathrm{.}90$ in years $3$ through year U$+2$ into the future$),$ and then be sold for $$50\mathrm{.}00$ in U$+2$ years $($where that $$50$ represents the present value of all dividends expected after U$+2$ years$).$ Compute the interest rate or expected return on this stock $($i$.$e$.,$ iterate to find the r that sets the sum of the present value of the future expected cash flows equal to the $$27\mathrm{.}50$ present value$).$
