From your subject line, I will guess that you are supposed to solve by using logs. To learn how to solve exponential equations, try

. . . . .

...and see where that leads.

so... 20000 = 5 x ln(1 + r)... I concur with this statement.

But how do you evaluate ln(1 + r) in a attempt to solve the equation for "r"?
