.18X+.08(250,000-X)=23,000
\n" ); document.write( ".18X+20,000-,08X=23,000
\n" ); document.write( ".10X=23,000-20,000
\n" ); document.write( ".10X=3,000
\n" ); document.write( "X=3,000/.10
\n" ); document.write( "X=$30,000 AMOUNT INVESTED @ 18%.
\n" ); document.write( "250,000-30,000=$220,000 AMOUNT INVESTED @ 8%.
\n" ); document.write( "PROOF:
\n" ); document.write( ".18*30,000+.08*220,000=23,000
\n" ); document.write( "5,400+17,600=23,000
