1. Understanding Demand

2. Law of Demand Describes the behavior of consumers Write down $.50, $1.00, $2.00. Next to each number write the number of sodas you would buy each week if the school sold them at those prices. Create a demand schedule Graph a demand curve “There is an inverse relationship between Price and Quantity”

3. Change in Demand v. Change in Quantity Demanded Visual 1.5 A movement from A to B is a change in quantity demanded. This movement along the curve is caused by a change in the price of the product. A movement from D to D1 or D to D2 is a change in Demand. This is caused by factors other than a chance in the price. Practice sketching change in quantity demanded v. a change in demand.

4. Change in Demand An increase in demand means people are willing and able to buy more at each price A decrease in demand means people are willing and able to buy less at each price. A movement from D to D1 (a shift right of the demand curve) is an increase in demand A movement from D to D2 (a shift left of the demand curve) is a decrease in demand.
