A manufacturer can produce 5,130 cell phones when a dollars is spent on labor and y dollars is spent on capital. The model that represents the cost of producing the cell phones is given by 95 x y z = 5130 A. Find the marginal cost model, in terms of x and y. dy dx = B. Find the marginal cost when $81 is spent on labor and $16 is spent on capital. Round the marginal cost to the nearest cent. $
