help! & if you can show your work so i can understand how- that would be great!

Computech Corporation is expanding rapidly and currently needs to retain all of its earnings; hence, it does not pay dividends. However, investors expect Computech to begin paying dividends, beginning with a dividend of 50,50 coming 3 years from today. The dividend should grow rapidly-at a rate of 50% per year-during Years 4 and 5 , but after Year 5 , growth should be a constant 10% per year. If the required return on Computech is 18%, what is the value of the stock today? Do not round intermediate caiculations. Round your answer to the nearest cent
