.10x+.09(24,000-x)=2,274
\n" ); document.write( ".10x+2160-.09x=2,274
\n" ); document.write( ".01x=2,274-2,160
\n" ); document.write( ".01x=114
\n" ); document.write( "x=114/.01
\n" ); document.write( "x=11,400 amount invested @ 10%.
\n" ); document.write( "24,000-11,400=12,600 amount invested @ 9%.
\n" ); document.write( "Proof:
\n" ); document.write( ".10*11,400+.09*12,600=2,274
\n" ); document.write( "1140+1134=2,274
\n" ); document.write( "2,274=2,274
