Peter is deciding between consuming good x and good y. at his current level of consumption, his marginal utility per dollar for good x is less than the marginal utility per dollar for good y. to achieve the consumer optimum, peter needs to?

Peter needs to consume more of the good Y.

Explanation:

Marginal utility is the additional satisfaction the individual has in consuming one unit more than one good. In this case, the marginal utility of consuming good y is greater than the marginal utility of consuming good x. Thus, to maximize its consumption, Peter will consume more of the good Y, which will give him greater satisfaction.
