A company's profit is described by the equation P(x)=-5x^2+300x+15,000 Where x is the price in dollars that the company charges for its product. What should the company charge for the product to generate the maximum profit?

A)$20

B)$30

C$50

D$60

$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.

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
