Answer 2

What do you think the answer is? :)

Answer 3

I'm confused on how to do this

Answer 4

Ok, so the equation is N(p) = 60p - p^2
And they're asking what the value of N(9) is.
N(p)
N(9)
They're saying that the value of p is 9.
So just substitute 9 for p in the equation:
N(9) = 60*9 - 9*9
Follow the order of operations and do the multiplication first, then subtract :)
