The cost of manufacturing x units of a commodity is given by the function C(X) = 50x + 400. X units are sold when the price per unit is 500 - 2x dollars. Use marginal analysis to approximate the profit or loss incurred in the manufacturing and selling of the 100th unit.
Added by Jennifer D.
Step 1
The price per unit is given by 500-2x, so when x=100, the price per unit is 500-2(100)=300 dollars. Therefore, the revenue generated by selling the 100th unit is 300 dollars. Show more…

Suppose that the marginal cost for x units of a product is MC = 4x + 50 and the cost of production is $1000 at a sale of 10 units. The marginal revenue is MR = 500. Find: a) The cost function, C(x). b) The revenue function, R(x). c) The profit function, P(x). d) The optimal level of production.

The cost function C(x) = 15,000 + 70x + (1000/x) gives the cost in dollars to produce x units of a commodity. a. Find the marginal cost when the production level is x = 100 units. When they produce 100 units, the marginal cost is _______ dollars. In other words, the approximate cost to produce the 101st unit is _______ dollars. b. Find the average cost per unit when they produce 100 units. When they produce 100 units, the average cost per unit is _______ dollars.

Suppose the cost function and the revenue function of a company for producing x units of products are C(x) = 80x + 180,000 dollars R(x) = -0.04x^2 + 600x i) Find the profit function; ii) Find the marginal profit function; iii) Find the marginal profit function at level of production x = 300.
