document.write( "Let's find the number of adults, x, first.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "If the number of adults is x, then the number of children is (116-x).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then your equation is for the total money\r\n" );
document.write( "\r\n" );
document.write( "    3x + 2.75*(116-x) = 335.25.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "From this equation\r\n" );
document.write( "\r\n" );
document.write( "    x = \"%28335.25-2.75%2A116%29%2F%283-2.75%29\" = 65 adults.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then the number of children is 112-65 = 47.\r\n" );
