USE AN IF statement on the time period to determine which dividend growth rate to use!

A fast-growing firm recently paid a dividend of $0.95 per share. The dividend is expected to increase at a 15 percent rate for the next three years. Afterwards, a more stable 10 percent growth rate can be assumed. If an 11 percent discount rate is appropriate for this stock, what is its value today? (Do not round intermediate calculations and round your final answer to 2 decimal places.) Complete the following analysis. Do not hard code values in your calculations. Assume that the period of nonconstant growth will last no more than 5 years
