Assume a consumer is spending all her income on two goods: X and Y. At the current consumption combination of the two goods, if the marginal utility per dollar spent on the last unit of good X exceeds that of the mary dollar spent on the last unit of good Y, what should the consumer do to maximize utility? Purchase more units of X and more units of Y. Decrease the price of good X. C Purchase more units of X and less units of Y. Increase income to buy more of both good Y and good X. E Nothing; utility is maximized at current consumption bundles
