Let x be the amount invested at 8%. Thus 12000-x would be the amount invested at 6%. The setup looks like this:
\n" ); document.write( ".08x + .06(12000-x) = 872
\n" ); document.write( "Now solve for x.
\n" ); document.write( ".08x + 720 - .06x = 872
\n" ); document.write( ".02x + 720 = 872
\n" ); document.write( ".02x = 152
\n" ); document.write( "x = $7600 invested at 8%
\n" ); document.write( "12000-x = $4400 invested at 6%
\n" ); document.write( "
\n" );
