### how to derive x (e to the power of x) via calculator instructions if other factors are known in exponential compounding

If the stock’s initial price is \$30 & its year-end price is \$35, then its continuously compounded annual rate of return is:
A.15.4%
B.14.5%
C.16.4%

The answer in notes is A. 15.4%.

Please explain how this is derived?

Also, does continuously compounded annual rate indicate the use of exponential formula??

If yes, please explain how to derive x (e to the power of x) via calculator (instructions) if other factors are known in continuously compounding rate (exponential formula)?
