made by the company is related
to the selling price of each
video game, x. Given the
equation below, find at whal
price the video game should be

To find the price at which the company should sell the video game to maximize profit, we need to find the vertex of the quadratic function y = -x^2 + 89x - 747.

The vertex of a quadratic function in the form y = ax^2 + bx + c is given by the formula:

Vertex = (-b/2a, c - b^2/4a)

Substituting the values from the given equation, we get:

Vertex = (-89/2*-1, -747 - 89^2/4*-1)

Solving for the x-value of the vertex, we get:

x = 44.5

Therefore, the video game should be sold for $44.50 to maximize profit.
