Scenаriо 5-8а - Suppоse the demаnd functiоn for good X is given by: Qdx =20-0.8Px + 0.8Py where Qdx is the quantity demanded of good X, Px is the price of good X, and Py is the price of good Y, which is related to good X.Refer to Scenario 5-8a. Using the midpoint method, if the price of good X is constant at $10 and the price of good Y decreases from $20 to $10, the cross price elasticity of demand is about
