Question 971371

of 8% compounded continuously.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~



In his post, @lwsshak3 gave the answer "approximately 9 years".


His calculations are correct, but the formulation of the answer is not adequate to the problem.


With the obtained value t = 8.66 years, the adequate answer is 8 years and 8 months.



This my correction is important, since it shows if a person, who solves the problem,
does understand correctly what he/she is doing.

How the word "principal" is written in the original post, tells me 
that the problem's creator does not know proper terminology in the area he writes about.
