At break-even, $\"+R%28x%29+=+C%28x%29+\"$
\n" ); document.write( " $\"+x+=+65+\"$
\n" ); document.write( " $\"+C%2865%29+=+25%2A65+%2B+650+\"$
\n" ); document.write( " $\"+C%2865%29+=+1625+%2B+650+\"$
\n" ); document.write( " $\"+C%2865%29+=+2275+\"$
\n" ); document.write( "and
\n" ); document.write( " $\"+R%2865%29+=+m%2Ax+%2B+b+\"$
\n" ); document.write( " $\"+m%2A65+%2B+b+=+2275+\"$
\n" ); document.write( " $\"+m+=+%28+2275+-+b+%29%2F65+\"$
\n" ); document.write( " $\"+R%28x%29+=+%28+%28+2275+-+b%29%2F65+%29%2Ax+%2B+b+\"$
\n" ); document.write( "Where $\"+b+\"$ is any number
