Can someone please help and explain this step by step using a FINANCIAL CALCULATOR, NOT EXCEL. I do not understand it and I really need help PLEASE!

NONCONSTANT GROWTH Computech Corporation is expanding rapidly and currently needs to retain of its earnings; hence, it does not pay dividends. However, investors expect Computech to begin paying dividends, beginning with a dividend of $1.00 coming 3 years from today. The dividend should grow rapidly at a rate of 46% per year-during Years 4 and 5; but after Year 5, growth should be a constant 5% per year. If the required return on Computech is 15%, what is the value of the stock today? Round your answer to the nearest cent. Do not round your intermediate calculations. $
