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 fiftieth product is $630, then it cost $6 30 to increase production from 49 to 50 units of output Suppose that the marginal cost C in dollars) to produce x digital cameras is given by C(x)=0 03x² - 6x + 350 How many digital cameras should be
produced to minimize marginal cost? What is the minimum marginal cost ?
