Amy recently moved to Philadelphia, where they developed a taste for drinking Americanos and eating danishes. Assume throughout this problem that the price of an Americano is held constant at $4.On the following graph, the purple curves (I1and I2) describe two of Amy's indifference curves. The lines BC1and BC2represent two budget constraints. Points X and Y show Amy's optimal consumption bundles subject to the budget constraints.
