The Playhouse Concert Hall has 523 seats. The Pink Ladies rock band is holding a concert there and charging $35.50 for each ticket. If the concert sells out, how much money will the band earn?

If each ticket costs $35.50, the total amount of money earned if the concert sells out is $35.50/ticket * 523 tickets = $<<35.50*523=18596.50>>18,596.50. Answer: \boxed{18596.50}.
