You can put this solution on YOUR website! the vertex form of a Parabola opening up(a>0) or down(a<0), . V(h, k)
Completing the Square to Obtain the Vertex Form:
y = ax^2 + bx + c = 0
p=-h^2+60h-400 = 0 30 the x-value for the Vertex
p = -(h - 30)^2 + 900 - 400= 0 = 900
p = -(h - 30)^2 + 500
V(30, 500)
h = $30, Profit $500
