    Answers will vary for the guess and test. You should have more than one guess before getting the correct answer.

    The solution that can be obtained by using graphing technology follows:

     
    This is a graph of one exponential function and a constant function. The exponential function is y equals 1.08 to the exponent x plus 2. The constant function is y equals 5. The intersection point of the two functions is approximately (18.9, 5).

    Thus, the approximate solution is x = 18.9.
