.08x=.10(5400-x)
\n" ); document.write( ".08x=540-.10x
\n" ); document.write( ".08x+.10x=540
\n" ); document.write( ".18x=540
\n" ); document.write( "x=540/.18
\n" ); document.write( "x=$3,000 invested @ 8%.
\n" ); document.write( "5,400-3,000=$2,400 invested @ 10%.
\n" ); document.write( "Proof:
\n" ); document.write( ".08*3,000=.10*2,400
\n" ); document.write( "240=240
\n" ); document.write( "
