Let $\"+r+\"$ = the rate for the $800 investment
\n" ); document.write( " $\"+r+%2B+.04+\"$ = the rate for the $2,000 investment
\n" ); document.write( "--------------
\n" ); document.write( "given:
\n" ); document.write( " $\"+2000%2A%28+r+%2B+.04+%29+=+800r+%2B+146+\"$
\n" ); document.write( " $\"+2000r+%2B+80+=+800r+%2B+146+\"$
\n" ); document.write( " $\"+1200r+=+146+-+80+\"$
\n" ); document.write( " $\"+1200r+=+66+\"$
\n" ); document.write( " $\"+r+=+.055+\"$
\n" ); document.write( " $\"+r+%2B+.04+=+.095+\"$
\n" ); document.write( "The rate for the $800 investment is 5.5%
