Answer

Explanation:

Step1: Find the derivative of the profit function

The profit function is (P(x)=202x - 5000-x^{2}). Using the power rule ((x^{n})^\prime=nx^{n - 1}), the derivative (P^\prime(x)=(202x)^\prime-(5000)^\prime-(x^{2})^\prime). Since ((ax)^\prime=a) (where (a = 202)) and ((c)^\prime=0) (where (c = 5000)), we have (P^\prime(x)=202-0 - 2x=202-2x).

Step2: Set the derivative equal to zero and solve for (x)

To find the critical points, set (P^\prime(x)=0). [ \begin{align*} 202-2x&=0\

  • 2x&=-202\ x& = 101 \end{align*} ]

Step3: Check the second - derivative

The second - derivative (P^{\prime\prime}(x)=(202 - 2x)^\prime=-2). Since (P^{\prime\prime}(x)=-2<0), the function (P(x)) is concave down at (x = 101), and (x = 101) is a point of maximum.

(101)
