Danny is an investment banker and has income I = 300. When prices are px = 10 and
py = 20, Danny consumes the bundle (x; y) = (6; 12).
1. Illustrate Danny's budget constraint and optimal bundle.
2. Suppose that prices change to px = 20 and py = 10. Draw Danny's new budget constraint on the same set of axes as his original budget constraint.
3. Danny is a smart guy and always makes utility maximizing choices. According to revealed preference, which bundles on his new budget constraint will he definitely not consume?
