Demand Wrap up

Part 1

1. Utility 
Definition: Ability of a good or service to be of use or give satisfaction to someone 
Example: Coffee has the utility of giving a person energy and usually will make them happier due to enjoying a delicious beverage

2. Complementary demand
Definition: The demand of an item that changes equally with an item that pairs with it 
Example: When the sales of hot dog go up due to a sale, the sales of hot dog buns will go up as well

3. Substitute demand
Definition: The demand for an object will have an inverse effect of a substitute item (items that have same utility) if the price goes up or down 
Example: If the price of Cheerios goes up, then the demand for frosted flakes would increase due to the similar utility

4. Elastic demand
Definition: Demand that will be effected greatly by a change in price
Example: As the price of cookies goes up, the demand will go down because the cookies are an unnecessary good

5. Inelastic demand
Definition: Demand that will not be effected by a change in price
Example: If the price of shampoo were to increase, the demand would remain static because shampoo is necessary to stay clean
