The marginal utility from the first burrito Bobby consumes is larger than the marginal utility from the first taco Bobby consumes. As a result, O Bobby will never consume tacos. O burritos and tacos are substitute goods for Bobby. O tacos are an inferior good for Bobby. O Bobby will consume a taco only if the price of a taco is noticeably less than the price of a burrito.Dynamic comparative advantage arises from O increasing opportunity cost. O learning-by-doing. O decreasing marginal benefit. O absolute advantage.Suppose that Freda receives $500 as income each week. If she spends the $500 each week and equalizes the marginal utility per dollar that she spend 0 Freda will reduce her marginal utility. O Freda is maximizing her total utility. O Freda's total utility will decline
