document.write( "(a)  Simple arithmetic.\r\n" );
document.write( "\r\n" );
document.write( "     The cost to produce 500 copies is  76 + 500*0.42 = 286 dollars.\r\n" );

document.write( "     The revenue when 500 copies sold is 500*0.62 = 310 dollars.\r\n" );
document.write( "\r\n" );
document.write( "     No loss.  The profit is 310-286 = 24 dollars.\r\n" );

document.write( "(b)  Let n be the number of copies produced and sold.\r\n" );
