.09X+.075(18,000-X)=1,560
\n" ); document.write( ".09X+1,350-.075X=1,560
\n" ); document.write( ".015X=1,560-1,350
\n" ); document.write( ".015X=210
\n" ); document.write( "X=210/.015
\n" ); document.write( "X=$14,000 INVESTED @ 9%.
\n" ); document.write( "18,000-14,000=$4,000 INVESTED @ 7.5%
\n" ); document.write( "PROOF:
\n" ); document.write( ".09*14,000+.075*4,000=1,560
\n" ); document.write( "1,260+300=1,560
\n" ); document.write( "1,560=1,560
\n" ); document.write( "
