.1x+.11(50,000-x)=5,200
\n" ); document.write( ".1x+5,500-.11x=5,200
\n" ); document.write( ".01x=5,200-5,500

\n" ); document.write( "x=-300/-.01
\n" ); document.write( "x=$30,000 invested @ 10%.
\n" ); document.write( "PROOF:
\n" ); document.write( ".1*30,000+.11(50,000-30,000)=5,200
\n" ); document.write( "3000+.11*20,000)=5,200
