Question 1:

Computech Corporation is expanding rapidly and currently needs to retain all of its earnings; hence, it does not pay dividends.

The dividend should grow rapidlyat a rate of 21% per yearduring Years 4 and 5, but after Year 5, growth should be a constant 6% per year. If the required return on Computech is 12%, what is the value of the stock today? Do not round intermediate calculations. Round your answer to the nearest cent.
