The amount A in an account after t years from an initial principle P invested at an annual rate r compounded continuously is given by A=Pe^r^t where r is expressed as a decimal. How many years will it take an initial investment of $1,000 to grow to $1,700 at the rate of 4.42% compounded continuously?
-----------
A=Pe^rt
1700 = 1000e^(0.0442t)
1.7 = e^(0.0442t)
Take the natural log to get:
0.0442t= ln(1.7)
t = 12.0052
