Draw indifference curves reflecting the following statements:
a) I like Coca-Cola and Pepsi-Cola. But if you take away half my Coca-Colas and double the number of Pepsi-Colas I have (or vice versa) I'm just as well off.
b) Advertising statements to the contrary, Coca-Cola and Pepsi-Cola are all the same to me. I don't care which one I get.
c) I always eat popcorn at the movies, and I never eat popcorn elsewhere.
