<font face="Times New Roman" size="+2">


A principal value, *[tex \Large PV], invested at *[tex \Large r%] per annum compounded *[tex \Large n] times per year for *[tex \Large t] years has a future value, *[tex \Large FV], of


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ FV\ =\ PV\(1\,+\,\frac{r}{100n}\)^{nt}]


Plug in the values you know and then solve for *[tex \Large t].  Hint: Take the log of both sides.
