Question
A company using first-degree price discrimination has a
demand curve given by P=100−2Q. If the marginal cost of production is $10 per unit, what is the total revenue if the company sells 20 units?Solution
Some students will find the price, P = 100-2(20) = 60 and then find TR= PQ = 60*20 = 1200. This is wrong. In the first-degree price discrimination, we need to find TR through integration of demand function.
