Question

a one time deposit is made into an account that pays an apr of 8.5% compounded continuously. How long does it take for the worth of the account to triple?

Answer 1

i dont recall if "apr" makes a difference but; the time to double and account tends to be ln(2)/rate

Answer 2

to triple is: ln(3)/rate
to 4-ple is: ln(4)/rate
to 5-ple ... ln(5)/rate ... and it goes on in a pattern like that :)

Answer 3
