John smedley, a careful maximizer of utility, consumes only two goods, peanut butter and broccoli. he had just achieved the utility-maximizing solution in his consumption of the two goods when the price of broccoli rose. assuming that this is treated as an income compensated price change (i. e., considering only the substitution effect of the price change), as he adjusts to this event: a) the marginal utility of peanut butter and of broccoli will rise. b) the marginal utility of peanut butter and of broccoli will fall. c) the marginal utility of peanut butter will fall, and the marginal utility of broccoli will rise. d) the marginal utility of peanut butter will rise, and the marginal utility of broccoli will fall.
