Scenario 5-2
Suppose the demand function for good X is given by: Qdx = 15 - 0.5Px - 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 5-2. Using the midpoint method, if the price of good X is constant at $10 and the price of good Y decreases from $5 to $3, what is the price elasticity of demand for good X? Is the demand elastic, unitary elastic, or inelastic?
