An editor has been allotted $60,000 to spend on the development and promotion of a new book. It is estimated that if x thousand dollars is spent on development and y thousand on promotion, approximately f(x,y) = 20x^(3/2)y copies of books will be sold. a. How much money should the editor allocate on development and how much on promotion to maximize sales? ( Ans x = 36, y =24) b. If this is done, estimate the maximum number of copies of the book that will be sold. ( Ans: 103680) For this question, use Langranges theorem.
