Let $\"x\"$ = amount he should invest @ 5.5%
\n" ); document.write( "Interest received first year:
\n" ); document.write( " $\".04%2A4000+%2B+.055x+=+.045%2A%284000+%2B+x%29\"$
\n" ); document.write( " $\"160+%2B+.055x+=+180+%2B+.045x\"$
\n" ); document.write( " $\"+.01x+=+180+-+160\"$
\n" ); document.write( " $\".01x+=+20\"$
\n" ); document.write( " $\"x+=+2000\"$
\n" ); document.write( "He must invest $2000 @ 5.5%\r
