Suppose Qxd = 9,500 - 2Px + 3Py - 4.5M , where Px = $100, Py = $50, and M = $2,000. Calculate the current quantity of good X demanded, then use it and the given information to calculate the own-price elasticity of demand at the current point on the demand curve, which is:
- 0.44
- - 0.21
- - 0.44
- 0.21
- - 2
