An amusement park charges $66 for adults and $42 for children. Yesterday, 8,760 people entered the park and there were twice as many children as adults. How many dollars were collected in ticket sales? Do not include the dollar sign in your answer. (The answer is an integer....therefore enter an integer for your answer, and do not use any notation to denote thousand. For example, 123456 should be entered as 123456 instead of 123,456)
