You are not a total math loser or you wouldn't have gotten this far. Let's be positive:

\n" ); document.write( "An investor puts $3000 in 2 CDs, one of which earns 5% annually and the other earns 4% annually. After 2 years he has earned $260. How much has he invested in each CD?
\n" ); document.write( ":
\n" ); document.write( "Let the amount invested at 5% be:x
\n" ); document.write( "Then the rest of the $3000 is invested at 4%: 3000-x
\n" ); document.write( ":
\n" ); document.write( "The interest formula is \"highlight%28I=Prt%29\", I=interest, P=principal, r=rate, t=time
\n" ); document.write( ".05(x)(2)+.04(3000-x)(2)=260
\n" ); document.write( ".10x+.08(3000-x)=260
\n" ); document.write( ".10x+240-.08x=260
\n" ); document.write( ".02x+240=260
\n" ); document.write( ".02x=260-240
\n" ); document.write( ".02x=20
\n" ); document.write( ".02x/.02=20/.02
\n" ); document.write( "x=1000
\n" ); document.write( "The amount invested at 5%:x=$1000
\n" ); document.write( "The amount invested at 4%:3000-x=3000-1000=$2000
\n" ); document.write( ":
\n" ); document.write( "Happy Calculating!!!
