How much money does the performing arts center earn in ticket sales for a sold-out event in both the main and secondary theaters? Enter the answer in the box.

The performing arts center can sell 720 tickets for its main theater and 75% more tickets for its secondary theater, which is 720 + (720 * 0.75) = 1260 tickets in total.

The total revenue from ticket sales for both theaters is 1260 tickets * $45.50 = $57,330.

Therefore, the performing arts center earns $57,330 in ticket sales for a sold-out event in both the main and secondary theaters.
