\r\n" );
document.write( "Use this equation\r\n" );
document.write( "\r\n" );
document.write( "    80 + 0.40*m = 50 + 0.90*m,\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "where \"m\" denotes miles.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The origin of this equation is so clear that I will not spend your time for explanations.\r\n" );

document.write( "\r\n" );
document.write( "    m =  = 60.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  60 miles.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "CHECK.  80 + 0.40*60 = 104 dollars = 50 + 0.9*60.    ! correct !\r\n" );
