Tracy is a marketing manager at humbert and humbert literary works. She has estimated that the likely demand for a new novel is well represented by equations Qd=10,000- 400(p) +10,000 x D + A/10. Qd is the number of books sold. P is the price that humbert and humbert charges. D is the dummy variable taking a value of 1 if the author is famous and a value of 0 otherwise. A is the dollars spent marketing the book. Assume marginal cost is 10$. Suppose that H and H decide not to market a new title by a famous author. What should H and H charge?
