\n" ); document.write( "Let $\"+b+\"$ = cost price of fan sold at 10% loss
\n" ); document.write( "---------------------
\n" ); document.write( " $\"+a+%2B+.1a+%2B+b+-+.1b+=+50000+\"$
\n" ); document.write( " $\"+1.1a+%2B+.9b+=+50000+\"$
\n" ); document.write( "------------------------
\n" ); document.write( "What if $\"+a+=+25000+\"$ and $\"+b+=+25000+\"$
\n" ); document.write( " $\"+1.1%2A25000+%2B+.9%2A25000+=+50000+\"$
\n" ); document.write( " $\"+27500+%2B+22500+=+50000+\"$
