Draw indifference curves to illustrate your teacher's preferences for hamburgers and beer.

a). Some days I find 2 beers and 1 hamburger equivalent in satisfaction no matter how much of either I consume.

b). Other days, I get neither positive nor negative satisfaction from beer, but love hamburgers.

c). My wife, Anne, eats one hamburger and washes it down with one beer. She has no interest in an additional unit of one item without an additional unit of the other.
