I feel like I saw a question like this where we had to find the expected number by using a similar function. I think the answer is A(280)=277.

Wait, does A(280) mean we plug in 280 to find this year's number? I thought it was the other way around.

I'm not entirely sure, but I think the function A(x) represents the number of people auditioning this year based on last year's auditions. So, A(280) should give us this year's number.

I remember we practiced similar problems where we had to adjust numbers based on last year's data. I think it's just subtracting 3 from 280.
