That also means, for every 1 dollar price increase, \"200%2F5\" fewer subscriptions.\r
\n" ); document.write( "\n" ); document.write( "
\r\n" );
document.write( "PRICE         HOW MANY SUBSCRIPTIONS\r\n" );
document.write( "40              2000\r\n" );
document.write( "400+d          2000-(200/5)d\r\n" );
document.write( "\r\n" );
document.write( "for d number of dollars\r\n" );
document.write( "
