Question 1153743
.
<pre>

6208 = {{{5377*e^(0.04*t)}}},  t is the time in years.


================>


{{{6208/5377}}} = {{{e^(0.04*t)}}}


1.154547 = {{{e^(0.04*t)}}}


Take the natural logarithm of both sides


ln(1.154547) = 0.04*t


t = {{{ln(1.154547)/0.04}}} = 3.59 of an year, approximately.


So, the answer is:  3.6 years is enough = 3 years and 219 days = 3 years, 7 months and 9 days 
                    (counting 365 days in an year and 30 days in a month).
