**Steve**, Wednesday, October 19, 2011 at 9:58amThe vertex of a parabola y=ax

^{2}+ bx + c occurs at x = -b/2a

So, when x = 40, we have p(x) = 5450

Duh. We just said that x = 40. How many dollars does that represent?

Now we want -5x^{2}+400x-2550 >= 4000

Think of the parabola. It opens downward. So, the portion above the line y=4000 is just a small cap, where

22.97 <= x <= 57.03
