Question 859839
Aleshia has invested an initial amount of $1200 at PNC Bank earning 3.14% compounded continuously.  When will the initial amount be doubled?
------------
FV = PV*e^rt
FV = 2*PV (the amount is not relevant)
e^rt = 2
{{{e^(0.0314t) = 2}}}
0.0314t = ln(2)
t = ln(2)/0.0314
t =~ 22.075 years
