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)

Best ResponseYou've already chosen the best response.1one year ago \[\Large\rm P(n)=250n^2 + 2500n  4000\]So the find `zeros`, we set the P(n) equal to zero.\[\Large\rm 0=250n^2 + 2500n  4000\]This will be easier to work with if we have no fancy coefficient on the squared term. So let's factor a 250 out of each term:\[\Large\rm 0=250(n^210n+16)\]Then divide the 250 away,\[\Large\rm 0=n^210n+16\]It looks like this will factor nicely! Confused by any of those steps?

Best ResponseYou've already chosen the best response.2250n^2 + 2500n  4000 = 0 n^2  10n + 16 = 0 (n  8)(n  2) = 0 The zeroes are (0,2) and (0,8). The values between these two points are places where the profit is positive. At these two points, the promoter breaks even. *** n^2  10n + 16 = 0 10/2 = 5 (5)^2 = 25 n^2  10n + 25 = 9 (n  5)^2 = 9 The maximum is when n  5 = 0, or n = 5. P(5) = 9 * 250 = 2250, or (5,2250). *** The access of symmetry is at n = 5.
