PLEASE ANSWER THIS FOLLOWING PROBLEM TO COMPLETE MY PROBLEM SET. PLEASE SHOW SOLUTIONS! THANKS! 5. Suppose that the demand for inkjet printers (Qdx) is estimated to be: Qd, = 1,000 - 5P, + 10P - 2P,, where Qdx = 2,800, P. (inkjet printers) = 80, Py (price of related good Y) =50, P. (price of related good Z) is 150. a. (5 points). Calculate the price elasticity of demand for inkjet printers. Is the demand for the inkjet printer elastic or inelastic? Interpret your result. (TIP: Use the point method formula and the slope associated with P.). b. (5 points). Calculate the cross-price elasticity of demand for inkjet printers in compare with the Price of related good Y. Is the good Y substitute? Or complement? Interpret your result. (TIP: Use the point method formula and the slope associated with P.). c. (5 points). Calculate the cross-price elasticity of demand for inkjet printers in compare with the Price of related good Z. Is the good Z substitute? Or complement? Interpret your result. (TIP: Use the point method formula and the slope associated with PJ
