The theater can hold 50 people and they charge $8.00 to watch a movie so on a sold - out night they make 50 * 8 = $400.00. On Tuesday night they only sold 24 tickets at $8.00 apiece so they made 24 * 8 = $192.00. If they make $400.00 on a sold - out night and they only made $192.00 on Tuesday then they lost 400 - 192 = $208.00.
Therefore, the answer is 208.
