\r\n" );
document.write( "the number of children tickets =   =  = 85.\r\n" );
document.write( "

\n" ); document.write( "\n" ); document.write( "Explanation.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "

\r\n" );
document.write( "Lets assume for a minute that all sold tickets were adult tickets.\r\n" );
document.write( "Then the revenue would be  142*9.10 = 1292.20 dollars.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It is  1292.20 - 960.70 = 331.50 dollars more than the actual revenue (! the numerator of my formula !)\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The difference is due to the difference between one adult and one children ticket, which is  9.10-5.20 = 3.90 dollars  \r\n" );
document.write( "                                                                      (! the denominator of my formula !).\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "So, replacing each adult ticket by one children ticket, we decrease this difference of 222.30 dollars by 3.90 dollars.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "By dividing one difference by another, you get the number of children tickets.\r\n" );
document.write( "
