Problem: Guy likes eggs on toasted bread, but he also likes omelettes, and is fine with eating bread on its own. His original optimal bundle is 6 eggs and 10 slices of bread. The price of bread goes down, but Guy's budget and the price of eggs remain unchanged. Guy's new optimal bundle includes 8 slices of bread. Draw a graph to illustrate this, including decomposition the price change into a substitution and income effect. Is egg an inferior good for Guy?
