A man invested half of his money at 5%, one-third of his money at 4%, and the rest of his money at 4.5%. If his total annual investment income was $550, how much had he invested?
\n" ); document.write( "***
\n" ); document.write( "let x=total amount invested
\n" ); document.write( "x/2=amt invested at 5%
\n" ); document.write( "x/3=amt invested at 4%
\n" ); document.write( "x-(x/2+x/3)=x-3x/6-2x/6=x/6=remaining amt invested at 4.5%
\n" ); document.write( "..
\n" ); document.write( "5%(x/2)+4%(x/3)+4.5%(x/6)=550
\n" ); document.write( "lcd:6
\n" ); document.write( ".05*3x+.04*2x+.045*x=3300
\n" ); document.write( ".15x+.08x+.045x=3300
\n" ); document.write( "x=12000
\n" ); document.write( "how much had he invested? $12,000 \n" ); document.write( "
\n" );
