The following function represents the profit P(n), in dollars, that a concert promoter makes by selling tickets for n dollars each: P(n) = -250n2 + 2,500n - 4,000 Part A: What are the zeroes of the above function, and what do they represent? Show your work. (4 points) Part B: Find the maximum profit by completing the square of the function P(n). Show the steps of your work. (4 points) Part C: What is the axis of symmetry of the function P(n)? (2 points)

    \( P(n) = -250n^2 + 2,500n - 4,000 \) 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.
