@zepdrix Hi, I saw your reply to this question a year ago and it wa really helpful, but I had trouble understanding it. Care to help again?

Oh, I already have part A. I was confused on Part B

\( P(n) = -250n^2 + 2,500n - 4,000 \) This is a parabola. You need to factor \( -250n^2 + 2,500n - 4,000 \) and solve for n to find the zeros. for part A.
