\r\n" );
document.write( "Let \"c\" be the cost for a cup, in dollars..\r\n" );
document.write( "Then the cost for a plate is (c+5) dollars.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Write an equation for total cost\r\n" );
document.write( "\r\n" );
document.write( "    12c + 8*(c+5) = 940  dollars.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Simplify, solve and find \"c\"\r\n" );
document.write( "\r\n" );
document.write( "    12c + 8c + 40 = 940,\r\n" );
document.write( "\r\n" );
document.write( "    12c + 8c = 940 - 40,\r\n" );
document.write( "\r\n" );
document.write( "       20c   =    900\r\n" );

document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  One cup costs $45.  One plate costs  $45 + $5 = $50.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "CHECK.   12*45 + 8*50 = 940  dollars,  total cost.   ! correct !\r\n" );
