document.write( "\r\n" );
document.write( ">>...she received twice as many dimes as quarters...<<\r\n" );
document.write( "\r\n" );
document.write( "That tells us that the number of dimes is twice the number or\r\n" );
document.write( "quarters, or 2x.\r\n" );
document.write( "\r\n" );
document.write( "since each quarter is worth 25 cents,\r\n" );
