Brockman Corporation's earnings per share were $3.50 last year, and its growth rate during the prior 5 years was 7.0% per year. If that growth rate were maintained, how many years would it take for Brockman's EPS to triple?

The number of years it would take is  

Step-by-step explanation:

From the question we are told that

         The earning per share  is   $3.50

          The growth rate is  r  =  7.0%

           The duration is

Generally the future value is mathematically represented as

 Where P is the present value

              n is the time period

         A is the future value which is mathematically evaluated as

substituting value

            $ 10.5 0

So

Taking log of both sides

the square root of what number? if you add that, then someone will probably answer the question.
