- Introduction to Calculus in Economics (continued): In the previous Problem Set question, we started looking at the cost function C (æ), the cost of a firm producing z items. An important microeconomics concept is the marginal cost, defined in (non- mathematical introductory) economics as the cost of producing one additional item. If the current production level is æ items with cost C (z), then the cost of computing h additionial (C(z+h)-C(z)) items is C (z + h). The average cost of those h items is . 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' (z). Use this function in the model below for the Marginal Cost function MC (x). Problem Set question: The cost, in dollars, of producing z units of a certain item is given by C (z) = 0.02a3 – 10z + 450. (a) Find the marginal cost function. MC (z) (b) Find the marginal cost when 50 units of the item are produced. The marginal cost when 50…arrow_forwardBack to Assignment Attempts: Keep the Highest: 1/4 3. The relationship between marginal and average costs Consider the following scenario to understand the relationship between marginal and average values. Suppose Edison is a professional basketball player, and his game log for free throws can be summarized in the following table. Fill in the columns with Edison's free-throw percentage for each game and his overall free-throw average after each game. Game Game Result Total Game Free-Throw Percentage Average Free-Throw Percentage 3/3 3/3 100 100 3/5 6/8 80 3 2/8 8/16 4 2/4 10/20 5/5 15/25 On the following graph, use the orange points (square symbol) to plot Edison's free-throw percentage for each game individually, and use the green points (triangle symbol) to plot his overall average free-throw percentage after each game. Note: Plot your points in the order in which you would like them connected. Line segments will connect the points automatically. 100 Tarrow_forwardQ.4 Marginal Cost is closely related to: (a) Total variable cost (b) Total cost (c) Total fixed cost (d) All of the abovearrow_forward
