The formula below gives N, the number of people who will go to a concert, as a function of p, the number of posters that are displayed to advertise the concert.

N(p)=60p-p^2

what is the value of N(9)?

N(p) = 60p - p^2

N(9) = 60(9) - (9)^2

N(9) = 540 - 81

N(9) = 459.

I believe the solution would be 459, thus 459 people will go to the concert.
