answer:To answer this managerial economics problem, let's break it down step by step, thinking through each part carefully. Hmm... I need to find the profit-maximizing quantity of books and the corresponding price, calculate the maximum profit for the publisher, determine the royalty income for the authors, and explain how a change in the royalty rate might affect these outcomes. Let me think about this carefully. Aha! This problem involves optimizing the publisher's profit, which is the difference between revenue and cost. The demand function for the books is given by P = 100 - 2Q, where P is the price per book and Q is the quantity of books. The cost of printing Q books is C(Q) = 50 + 20Q. The publisher pays authors Smith and Wesson a total royalty rate of 15% on the revenue from the books. Wait, let me break this down first - what does it really mean to maximize profit? It means I need to find the quantity of books (Q) that results in the highest possible profit, considering both the revenue generated from selling the books and the costs associated with printing them. Oh, I see! To start, I need to define the revenue function. The revenue (R) is given by the price per book (P) times the quantity of books (Q). Given the demand function P = 100 - 2Q, I can write the revenue function as R = (100 - 2Q) * Q = 100Q - 2Q^2. Now, let's define the cost function, which is given as C(Q) = 50 + 20Q. This represents the total cost of printing Q books. Next, I'll define the profit function. Profit (π) is the difference between revenue and cost, so π = R - C. Substituting the expressions for R and C, I get π = (100Q - 2Q^2) - (50 + 20Q) = 100Q - 2Q^2 - 50 - 20Q = 80Q - 2Q^2 - 50. To find the profit-maximizing quantity (Q*), I need to find the derivative of the profit function with respect to Q and set it to zero. The derivative of π with respect to Q is dπ/dQ = 80 - 4Q. Setting this equal to zero gives 80 - 4Q = 0, which simplifies to 4Q = 80, and thus Q* = 20. Aha! Now that I have the profit-maximizing quantity, I can find the corresponding price (P*). Substituting Q* = 20 into the demand function P = 100 - 2Q gives P* = 100 - 2 * 20 = 100 - 40 = 60. Let me calculate the maximum profit for the publisher. Substituting Q* = 20 into the profit function gives π* = 80 * 20 - 2 * 20^2 - 50 = 1600 - 800 - 50 = 750. Next, I need to determine the royalty income for authors Smith and Wesson at the profit-maximizing quantity. The royalty rate is 15% of the revenue. First, I calculate the revenue at Q* = 20: R = P* * Q* = 60 * 20 = 1200. Then, the royalty income is 0.15 * 1200 = 180. Oh, I see! To explain how a change in the royalty rate might affect the publisher's profit-maximizing quantity and the authors' royalty income, let's consider the impact of the royalty rate on the profit function. If the royalty rate changes, it affects the publisher's profit function, but it does not change the optimal quantity Q* because the marginal revenue is not affected by a constant multiplier. Therefore, the profit-maximizing quantity Q* remains the same. However, the authors' royalty income would change directly with the royalty rate. If the royalty rate increases, the authors' royalty income increases, and if it decreases, their royalty income decreases. For example, if the royalty rate increases to 20%, the new royalty income would be 0.20 * 1200 = 240. In summary: - The profit-maximizing quantity Q* is 20. - The corresponding price P* is 60. - The maximum profit for the publisher is 750. - The royalty income for authors Smith and Wesson at the profit-maximizing quantity is 180. - A change in the royalty rate affects the authors' royalty income but not the profit-maximizing quantity. By carefully thinking through each step of the problem, I've been able to find the optimal quantity and price, calculate the maximum profit, determine the royalty income, and understand the impact of a change in the royalty rate. This step-by-step approach helps ensure that I've considered all aspects of the problem and arrived at a comprehensive solution.
