Answer:

$30

Step-by-step explanation:

To answer this, maximize the profit function P(x)= -5x^2 + 300x + 15,000.  Note that this is a quadratic function with coefficients -5, 300, 15000.  Find the x-coordinate of the vertex:  It is

        -300

x = ------------ = 30, and because coefficient a is negative, we know that

        2(-5)               the graph opens downward and the max is at x = 30.

Conclusion:  charging $30 for its product will maximize the profit.
