Secondly, after the inflation calculations, write all where and how did you did your project. Your prices may increase, decrease, or stay the same. There is no correct answer for the price changes. Your job is to think about explanations for why prices increased, decreased, or stayed the same. If an item went on sale or was discontinued, eliminate that item from the inflation calculation but discuss why that might have happened. What type of economic (or other) reason(s) can you give to explain the differences? Think about a. type of product b. the type of store c. the level of competition of the store in your area d. the type of buyers in the store e. weather conditions f. seasonal demand
