You can put this solution on YOUR website!
Use the relation:
\n" ); document.write( "( Profit ) = ( Revenue ) - ( Cost )
\n" ); document.write( " $\"+P%28x%29+=+R%28x%29+-+C%28x%29+\"$
\n" ); document.write( " $\"+.085x+-+1.1+=+.2x+-+C%28x%29+\"$
\n" ); document.write( "Add $\"+C%28x%29+\"$ to both sides
\n" ); document.write( " $\"+C%28x%29+%2B+.085x+-+1.1+=+.2x+\"$
\n" ); document.write( "Subtract $\"+.085x+\"$ from both sides
\n" ); document.write( " $\"+C%28x%29+-+1.1+=+.115x+\"$
\n" ); document.write( "Add $\"+1.1+\"$ to both sides
\n" ); document.write( " $\"+C%28x%29+=+.115x+%2B+1.1+\"$
\n" ); document.write( "-------------------------
\n" ); document.write( "Check:
\n" ); document.write( "Say $\"+x+=+1000+\"$
\n" ); document.write( " $\"+P%281000%29+=+R%281000%29+-+C%281000%29+\"$
\n" ); document.write( " $\"+.085x+-+1.1+=+.2x+-+C%28x%29+\"$
\n" ); document.write( " $\"+85+-+1.1+=+200+-+C%28x%29+\"$
\n" ); document.write( " $\"+83.9+=+200+-+C%28x%29+\"$
\n" ); document.write( " $\"+C%281000%29+=+116.1+\"$
\n" ); document.write( "and
\n" ); document.write( " $\"+C%28x%29+=+.115x+%2B+1.1+\"$
\n" ); document.write( " $\"+C%281000%29+=+115+%2B+1.1+\"$
\n" ); document.write( " $\"+C%281000%29+=+116.1+\"$
\n" ); document.write( "OK \n" ); document.write( "

\n" );
