Let n be the number of pieces. We want:\r
\n" ); document.write( "\n" ); document.write( "850 + 4n < 9n\r
\n" ); document.write( "\n" ); document.write( "850 < 5n\r
\n" ); document.write( "\n" ); document.write( "170 < n\r
\n" ); document.write( "\n" ); document.write( "n > 170\r
\n" ); document.write( "\n" ); document.write( "So 171 pieces or more must be sold to make a profit.
\n" ); document.write( "
\n" );
