Andrew has an income of $30 he spends on cupcakes and cakes. The price of a cupcake is $5. Suppose that Andrew has the following preferences depicted below:
a. With this in mind, draw Andrew€™s demand curve for cake.
b. When the price of cake changes, which effect is stronger, the substitution effect or the income effect? Give your answer for every price change depicted in the figure.
c. If Andrew€™s preferences shifted toward not distinguishing between cake and cupcakes (i.e., if they became closer substitutes), all his indifference curves would become flatter. How would Andrew€™s demand curve for cake change?
