Let $\"+P+\"$ = his investment
\n" ); document.write( "His return from 5% investment is:
\n" ); document.write( " $\"+%281%2F2%29%2AP%2A.05+\"$
\n" ); document.write( "------------------------
\n" ); document.write( "His return from 4% investment is:
\n" ); document.write( " $\"+%281%2F3%29%2AP%2A.04+\"$
\n" ); document.write( "--------------------------
\n" ); document.write( "His return from 3.5% investment is:
\n" ); document.write( " $\"+%281%2F6%29%2AP%2A.035+\"$
\n" ); document.write( "-----------------
\n" ); document.write( " $\"+%281%2F2%29%2AP%2A.05+%2B+%281%2F3%29%2AP%2A.04+%2B+%281%2F6%29%2AP%2A.035++=+795+\"$
\n" ); document.write( "Multiply both sides by $\"+6+\"$
\n" ); document.write( " $\"+.15P+%2B+.08P+%2B+.035P+=+4770+\"$
\n" ); document.write( " $\"+.265P+=+4770+\"$
\n" ); document.write( " $\"+P+=+18000+\"$
\n" ); document.write( "$18.000 was his investment\r
