The demand for good X is estimated to be QXd = 10,000 – 4PX + 5PY + 2M + AX, where PXis the price of X, PY is the price of good Y, M is income and AX is the amount of advertisingon X. Suppose the present price of good X is $50, PY = $100, M = $25,000, and AX = 1,000units. What is the own-price elasticity of demand for good X?
Note
The demand for good X is estimated to be QXd = 10,000 - 4PX + 5PY + 2M + AX, where PXis the price of X, PY is the price of good Y, M is income and AX is the amount of advertisingon X. Suppose the present price of good X is $50, PY = $100, M = $25,000, and AX = 1,000units. the own-price elasticity of demand for good X isA. -0.003.
