F= future value
P=present value
F=p*e*rt
 Read below to understand continuous compounding

F=2p

2p =p * e^.034t
Divide both sides by p

2= e^.034t  t is the time
You have to know properties of log and Ln to solve this

Get Ln of both sides

Ln of 2 = Ln of e^.034t
Ln of 2 = .034r* Ln of e
Using your calculator you will find Ln of 2 is .693 and Ln of e is one
.693 = .034 t
T = time = years = .693/.034. = 20.4 which means it takes around 20.4 years for the money to double.
