If the price of A decreases, while the price of B and the consumer's income stay the same, we
would expect
D. MU/P of A to decrease, and the consumer will thus buy less of A.

price in the consumer-behavior model and noting
A. the increase in the utility-maximizing quantity of that product demanded.

the price of X increases, then the MU/P of X will

212. The reason the substitution effect works to encourage a consumer to buy less of a product
when its price increases is that

the rational consumer will most likely
