Question 862338: The marginal cost of a product can be thought of as the cost of producing one additional unit of output. For example, if the marginal cost of producing the 50th product is $6.20, it cost $6.20 to increase production from 49 to 50 units of output. Suppose the marginal cost C(in dollars) to produce x thousand mp3 players is given by the function C(x)=x^2-100x+7600.
A.How many players should be produced to minimize the marginal cost?
B.What is the minimum marginal cost?

Hi

Underlining demonstrating completing the Square

C(x)=x^2-100x +7600 = (x-50)^2 -2500 + 7600 = (x-50)^2 + 5100

A. 50

B. $5100
