document.write( "Let x = the number of the $24.99 cartridges sold.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then the number of the $15.99 cartridges is (47-x).\r\n" );

document.write( "\r\n" );
document.write( "    24.99x + 15.99*(47-x) = 940.53.\r\n" );

document.write( "    x =  = 21.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  21 cartridge at $24.99  and  the rest, 47-21 = 26 cartridges at $15.99.\r\n" );
