Arrange the following steps in the correct order to analyze the impact of a price increase in muffins on the demand for coffee, a complementary good.

To analyze how a price increase in muffins affects the demand for coffee, we start by understanding that muffins and coffee are complementary goods, meaning they are often consumed together. When the price of muffins goes up, fewer people may want to buy them because they are more expensive. As a result, since people usually enjoy coffee with their muffins, the demand for coffee is likely to decrease as well. For example, if a café raises the price of muffins, customers might decide to buy fewer muffins and, consequently, buy less coffee too. This shows how the price change of one good can influence the demand for another good that is closely related.
