Question 1097475
<br>You didn't specify simple or compound interest.  The answers posted so far assume simple interest (although one of the answers used the wrong amount of interest).<br>
If it is compound interest compounded annually, then the equation is
{{{6000(1+r)^6= 6000+2340}}}
{{{6000(1+r)^6 = 8340}}}
{{{(1+r)^6 = 1.39}}}
{{{1+r = 1.054418}}}<br>
The interest rate r is
{{{1.054418-1 = .054418}}}
or about 5.44%.
