Question - Suppose that the supplies of products A and B are given by: QA = 20 +2PA, and QB = -50 + PB, and that the demands for A and B are given by the following equations (in inverse demand form): PA = 2,000 - 0.5QA + 4PB and PB = 500 - 2QB + PA. What are the equilibrium prices and quantities of A and B? Show your work.
