The owners of a theatre receive $5 per ticket sold to a certain performance. How much did the theatre owners receive from ticket sales?

(1) The total revenue from ticket sales was $700
(2) If 30 more tickets had been sold, the theater owners would have received 30% more money from ticket sales.

My question:

Ticket sales was $700, so (1) is sufficient. And (2) is sufficient so =
(D) is correct, unless you are saying that $700 came from more than one
performance. ???

That's absolutely right AEK,

There is nothing that suggests that (1) relates the revenues from a single performance. We are not permitted to assume anything in data sufficiency.

Take care,
