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).

\n" ); document.write( "If it is compound interest compounded annually, then the equation is
\n" ); document.write( "\"6000%281%2Br%29%5E6=+6000%2B2340\"
\n" ); document.write( "\"6000%281%2Br%29%5E6+=+8340\"
\n" ); document.write( "\"%281%2Br%29%5E6+=+1.39\"
\n" ); document.write( "\"1%2Br+=+1.054418\"

\n" ); document.write( "The interest rate r is
\n" ); document.write( "\"1.054418-1+=+.054418\"
\n" ); document.write( "or about 5.44%.
\n" ); document.write( "
\n" );
