As you know there are 6 things that cause shift in demand: consumer income, consumer tastes, substitutes,complements, expectations, and number of consumers. I want you to pick four of the six to illustrate. For each situation you draw you should describe the situation and say whether or not it leads to increase or a decrease in demand for the item you are describing For example for complementary goods you might show a sale on peanut butter which causes people to buy more jelly. This will cause an increase in demand
