The function C(x) = 400x – 0.2x2 represents the total costs for a company to produce a product, where C is the total cost in dol
lars and x is the number of units sold. Which statement is true?. A. One thousand units have the minimum cost of $200,000.. B. One thousand units have the maximum cost of $200,000.. C. Two thousand units have the minimum cost of $800,000.. D. Two thousand units have the maximum cost of $800,000..
To determine the maxima and minima of the polynomial, differentiate the given based on x and equate to 0. C(x) = 400x - 0.2x² dC(x) / dt = 400 - 0.4 x = 0 The value of x is 1000. This is the value of the maxima. As the value of C(x) continously becomes lesser as the value of x is set higher, the minima is not identified. Substitute x to the original equation, C(x) = (400)(1000) - 0.2(1000²) = $ 200,000 Thus, the answer is letter B.
