The marginal cost C'(Q) (in dollars per unit) of producing q units is given in the following table. Round your answers to the nearest integers. (a) If fixed cost is $17,000, estimate the total cost of producing 400 units. The cost of producing 400 units is $. (b) To the nearest dollar, how much would the total cost increase if production were increased one unit, to 401 units? The total cost increase If production were increased one unit is $
