Marginal utility can be described as the additional utility that a person gets by consuming one additional unit of product. From the given above question , we know that for Todd each pair of jeans cost $50 and the marginal utility that he gets from the last pair of jeans is 200, so if we know that each cowboy hat cost $100, then the marginal utility from the last cowboy hat would be 100 x 4 = 400 .
