Shirley Sixpack, as you will recall, thinks that two 8-ounce cans of beer are exactly as good as one 16-ounce can of beer. Suppose that these are the only sizes of beer available to her and that she has $30 to spend on beer. Suppose that an 8-ounce beer costs $.75 and a 16-ounce beer costs $1. On the graph below, draw Shirley€™s budget line in blue ink, and draw some of her indifference curves in red.
Shirley Sixpack, as you will recall, thinks that two 8-ounce

(a) At these prices, which size can will she buy, or will she buy some of each? ____________
(b) Suppose that the price of 16-ounce beers remains $1 and the price of 8-ounce beers falls to $.55. Will she buy more 8-ounce beers? _________
(c) What if the price of 8-ounce beers falls to $.40? How many 8-ounce beers will she buy then? _________
(d) If the price of 16-ounce beers is $1 each and if Shirley chooses some 8-ounce beers and some 16-ounce beers, what must be the price of 8-ounce beers? __________
(e) Now let us try to describe Shirley€™s demand function for 16-ounce beers as a function of general prices and income. Let the prices of 8-ounce and 16-ounce beers be p8 and p16, and let her income be m. If p16 2p8, then the number of 16-ounce beers she will demand is ____. If p16 =
____ p8, she will be indifferent between any affordable combinations.
