olga nikolaevna [1]

Using the vertex of the quadratic equation, it is found that the maximum profit she can earn is of $106.

<h3>What is the vertex of a quadratic equation?</h3>

A quadratic equation is modeled by:

y = ax^2 + bx + c

The vertex is given by:

(x_v, y_v)

In which:

x_v = -\frac{b}{2a}

y_v = -\frac{b^2 - 4ac}{4a}

Considering the coefficient a, we have that:

  • If a < 0, the vertex is a maximum point.
  • If a > 0, the vertex is a minimum point.

In this problem, her profit is modeled by:

P(x) = -x^2 + 14x + 57

Which is a quadratic equation with coefficients a = -1, b = 14, c = 57, hence, her maximum profit in dollars is given by:

y_v = -\frac{14^2 - 4(-1)(57)}{4(-1)} = 106
