\r\n" );
document.write( "Let H be the number of hot dogs and C be the number of chips.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then from the condition we have this system of 2 equations\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "H + C = 20     (1)    (same as the number of people)\r\n" );
document.write( "\r\n" );
document.write( "H = 4C         (2)    (four times as many hot dogs as buckets of chips)\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "From equation (2), substitute the expression H = 4C into equation (1)\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "4C + C = 20,\r\n" );
document.write( "\r\n" );
document.write( "5C     = 20,\r\n" );
document.write( "\r\n" );
document.write( "C      = 20/5 = 4.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  4 buckets of chips and 4*4 = 16 hot dogs.\r\n" );
