Best ResponseYou've already chosen the best response.0The compound interest formula is: FV=PV(1+i)^n Where FV is the final value, PV is the present value, i is the interest rate and n is the time (in years). Are you able to try and work towards an answer now?

Best ResponseYou've already chosen the best response.0Use the formula I just gave you. 5000(1+0.0625)^n=10000 Do you agree so far?

Best ResponseYou've already chosen the best response.0So divide through by 5000 to get (1.0625)^n=2 Then use logs to find n. Are you able to finish the question?
