Answer to Question 1

The extent to which a firm can exercise market power is limited by the ease with which consumers can substitute for its product.

Answer to Question 2

The marginal benefit from each additional dollar spent should be equal across various goods in order to maximize overall well-being. If these marginal units (last units) of satisfaction are not equal, then the consumer can be made better off by shifting consumption toward the good that yields more satisfaction at the margin. Hence, equilibrium occurs at the point where satisfaction from the last dollar spent is equal for all goods. This is the reasoning behind the old phrase getting the most bang for the buck.
