2. A monopolist is currently selling 50 units at $100 each. In order to sell one more unit, he would have to cut the price to $99. What is his marginal revenue? A)$100 B)$99 C)$75 D)$49 E)$29

3. Why is that? To sell one more unit he needs to cut price by $1. He gets $99 for the extra unit he sells, but he loses $1 on each of the 50 units he was selling at $100. So his marginal revenue is $99-50=$49.
