    really need help!!!!!

    I really have to figure out the answers to these questions and i dont know where to start. I dont know how to draw the marginal benefit and marginal cost curves for this question.

    a.Sketch a marginal benefit and marginal cost diagram, with “billions of units of security per month” on the horizontal axis and the marginal cost and marginal benefit, measured in “all other goods per unit of security” on the vertical axis. What is the relationship between this diagram and the production possibilities diagram to the right? What is the pre-9-11 efficient quantity of security services? How is this quantity determined?

    b.How did the catastrophic events of 9-11 affect the marginal benefit and marginal cost diagram? (Hint: One of the curves shifted). Draw a diagram showing the post-9-11 marginal benefit and marginal cost diagram. What is the new efficient quantity of security services? How does this new point relate to the discussion in the Wall Street Journal article about the costs being imposed on the public from enhanced security?
