\r\n" );
document.write( "The problem says that the amount D of the Carbon-14 remaining in the artifact\r\n" );
document.write( "is 92%, or 0.92, of the original amount D0.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "In other words, according to the problem, D/D0 = 0.92.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Having it, apply the given formula: the age of the artifact is\r\n" );
document.write( "\r\n" );
document.write( "    A =  =  = use your calculator = 688.5 years = 690 years (ap-proximately.\r\n" );
