Question 18
Alex Potter owns the only well in a town that produces clean drinking water. He faces the following demand P=200-2Q, and marginal cost MC=50+2Q, marginal revenue MR= 200-4Q curves. In order to maximize profits, Alex should charge a price of
$150 at the profit maximizing quantity with a marginal revenue equal to $150.
$100 at the profit maximizing quantity with a marginal revenue equal to $150.
$100 at the profit maximizing quantity with a marginal revenue equal to $100.
$150 at the profit maximizing quantity with a marginal revenue equal to $100.

Consider the graph above. If the demand curve intersects the marginal & average cost curve at 100 units, calculate the profit-maximizing quantity. Profit-maximizing quantity =

A small village has only one Italian restaurant. The daily demand for dinners in this restaurant is P=120-2Q, where P is the price in £ and Q is the number of dinners. It has a fixed cost of £300 and a marginal cost of £10 for the first 15 dinners. If it wants to produce more than 15 dinners, it must pay overtime wages to its workers, with the marginal cost rising to £20. What is the maximum amount of profit the restaurant can earn? Illustrate your answer on a diagram.

Here q is measured in millions of barrels a day. OPEC marginal cost per barrel is $15. What is OPEC’s optimal level of production? What is the prevailing price of oil at that level? Many experts contend that maximizing short-run profit is counterproductive for OPEC in the long run because high price reduces buyers to conserve energy and spur competition and new exploration that increases the overall supply of oil. Suppose that the demand curve just described will remain unchanged only if oil prices stabilize at $65 per barrel or below. If oil price exceeds this threshold, long run demand (over a second five year-period) will be curtailed to P = 135 – 2.5q. OPEC seeks to maximize its total profit over the next decade. What is the optimum output and price policy? (assume all values are present values)arrow_forward
