Amount= 5000
\n" ); document.write( "years=n
\n" ); document.write( "compounded 1
\n" ); document.write( "Rate = 8.5
\n" ); document.write( "Amount = P*((n+r)/n)^n
\n" ); document.write( "
\n" ); document.write( "5000 = 2000 *( 1 + 0.09 )^ n
\n" ); document.write( "2.5 = *( 1 + 0.09 )^ n
\n" ); document.write( "ln 2.5 = n ln 1.09
\n" ); document.write( " 0.92 = n 0.08
\n" ); document.write( " 11.23 = n
\n" ); document.write( "
\n" ); document.write( "
\n" );
