Hi,



The formula is:



A = Pe^(rt) (Where A is the future value, P is the initial amount (principal), r is the interest rate expressed as a decimal, and t is the time in years.



So, let鈥檚 solve for t.



A/P = e^(rt)



ln (A/P) = rt



t= ln(A/P)/r



= ln (20000/7000)/.05 (You鈥檒l need a calculator to do this arithmetic.)



= 20.996 or rounded off 21 years.
