Let $\"+C+\"$ = production costs
\n" ); document.write( "Let $\"+S+\"$ = income from sales of books
\n" ); document.write( "Let $\"+n+\"$ = number of books sold
\n" ); document.write( "---------------------------------------
\n" ); document.write( "(1) $\"+C+=+11n+%2B+15210+\"$
\n" ); document.write( "(2) $\"+S+=+18.5n+\"$
\n" ); document.write( "-------------------------
\n" ); document.write( "Set $\"+C+=+S+\"$
\n" ); document.write( " $\"+11n+%2B+15210+=+18.5n+\"$
\n" ); document.write( " $\"+7.5n+=+15210+\"$
\n" ); document.write( " $\"+n+=+2028+\"$
\n" ); document.write( "----------------
\n" ); document.write( "The publisher must sell 2028 books so
\n" ); document.write( "that cost = money from sales
\n" ); document.write( " \n" ); document.write( "
