I am confused as to how to approach the problem- any assistance is appreciated! Thank you

1. A consumer has standard, non-satiated preferences over two goods, X and Y. The graph below shows the Optimal bundle (A) for a given budget line BLA. Show that X and Y cannot both be inferior goods for the same income change. [Please add elements to the graph and explain them briey. ] Units of Y Units of X 2. We often assume that consumer preferences are (1) complete, (2) non-satiated, (3) transitive, (4) continuous, and (5) convex. Pick one of these assumptions and describe an example of consumer behavior violating that assumption 3. A government considers raising payroll taxes which are nominally paid by rms. Proponents of the payroll tax argue that this is preferable to an equivalent income tax, because it burdens rms instead of workers. Do you agree? Why? [No need for graphs or calculations, a short text explanation is sufficient.) . . . MR = p + \"1\"- 4. The marginal revenue of a monopolist IS AG What is the marginal revenue of a rm subject to perfect competition? Explain why the two (MR under monopolistic vs. perfect competition) differ
