1. Suppose that the total revenue function for a commodity is R(x) = 25x - 0.5x2. a. Find R(10) and tell what it represents. Find the marginal revenue function. C. Find the marginal revenue at x = 10, and tell what it predicts about the sale of the next unit. d. Find R(11) - R(10) and explain what it represents. 2. a. Find the x intercept of the marginal revenue function. h Determine the number of units that must be sold to maximize total revenue. C. What is the maximum revenue? 3. Graph R(x) and MR(x) in the window xmin = 0, xmax = 50, ymin = -50, and ymax = 350. Write a sentence or two that explains how the graphs are related
