Suppose a monopolist producing self-cleaning jackets can sell 20 jackets at $100, and 21 jackets at $98. The monopolist is unable to price discriminate, so in order to sell a total of 21 jackets, the price per jacket must be $98.
1-When charging $100 per jacket, total revenue is?
2-When charging $98 per jacket, total revenue is?
3-So the marginal revenue of selling the 21st jacket is?
4-In the case of any firm facing a downward sloping demand curve, marginal revenue is always?
