.10x+.08(60,000-x)=5,800
\n" ); document.write( ".10x+4,800-.08x=5,800
\n" ); document.write( ".02x=5,800-4,800
\n" ); document.write( ".02x=1,000
\n" ); document.write( "x=1,000/.02
\n" ); document.write( "x=50,000 amount invested @ 10%.
\n" ); document.write( "60,000-50,000=10,000 amount invested @ 8%.
\n" ); document.write( "Proof:
\n" ); document.write( ".10*50,000+.08*10,000=5,800
\n" ); document.write( "5,000+800=5,800
\n" ); document.write( "5,800=5,800
