OK Fencing Co. is experiencing a high growth period. As such, they expect dividends to grow at 12% per year for the next 3 years. After that the dividend growth rate should slow to about 4%. The required rate of return is 15% and they just paid a dividend of $1.80, what is the current share price? The answer should be $19.40 but I am not sure how to get here. I am using a TI-84 Plus CE calculator.
