How long, to the nearest day, will it take $25,000 to grow to $500,000 at 9% annual interest rate compounded monthly?
----
A(t) = P(1+(r/n))^(n*t)
------
500000 = 25000(1+(0.09/12))^(12*t)
------
(1.0075)^(12t) = 20
----
12t = log(20)/log(1.0075)
----
12t = 400.927
t = 33.4105 years
-------
t = 33 yrs + 0.4105*365 days = 33 yrs 149.9 days = 33 yrs 150 days
