42)Marginal utility analysis predicts a downward - sloping demand curve for good X because 42) A) as P X rises, the consumer increases purchases of X such that MU X /P X is equal to MU/P for all other products. B) as P X falls, the consumer increases purchases of X such that MU X /P X is equal to MU/P for all other products. C) all demand curves are downward sloping, regardless of the behaviour of consumers. D) utility - maximizing consumers equate marginal utility received for each product consumed. E) as P X falls, the ratio MU X /P X becomes smaller, causing the consumer to purchase more of good X. Answer:B
