If the current production level is x items with cost C(x), then the cost of computing h additionial items is C(x+h). The average cost of those h items is (C(x+h)−C(x))/h . As we analyze the cost of just the last item produced, this can be made into a mathematical model by taking the limit as h→0, i.e. the derivative C′(x). Use this function in the model below for the Marginal Cost function MC(x).

Question

If the current production level is x items with cost C(x), then the cost of computing h additionial items is C(x+h). The average cost of those h items is (C(x+h)−C(x))/h . As we analyze the cost of just the last item produced, this can be made into a mathematical model by taking the limit as h→0, i.e. the derivative C′(x). Use this function in the model below for the Marginal Cost function MC(x).

 

The cost, in dollars, of producing x units of a certain item is given by

(b) Find the marginal cost when 30 units of the item are produced.
The marginal cost when 30 units are produced is $ Number
(c) Find the actual cost of increasing production from 30 units to 31 units.
The actual cost of increasing production from 30 units to 31 units is $ Number
