\n" ); document.write( "Let $\"+n+\"$ = number of burgers sold in one week
\n" ); document.write( "For a one week period:
\n" ); document.write( " $\"+P+=+R+-+C+\"$
\n" ); document.write( " $\"+R+=+1.8n+\"$
\n" ); document.write( " $\"+C+=+.95n+%2B+475+\"$
\n" ); document.write( " $\"+P+=+1.8n+-+%28+.95n+%2B+475+%29+\"$
\n" ); document.write( " $\"+P+=+1.8n+-+.95n+-+475+\"$
\n" ); document.write( " $\"+P+=+1.75n+-+475+\"$
\n" ); document.write( "The \"break even point\" ( zero profit ) is when:
