\n" ); document.write( "\n" ); document.write( "HINT: You can group the tickets in sets in a way each set contains  8  adult tickets and  1  child ticket.
\n" ); document.write( "            Then each set is worth  8*5 + 2.50 dollars = 42.50 dollars,  and the number of sets is  \"850%2F42.50\" = 20.\r
