Explanation:

1. Demand: Demand refers to the quantity of a good or service that consumers are willing and able to buy at various prices during a given period. In the case of electric cars, as consumer awareness of environmental - friendliness and government incentives increase, the demand for electric cars rises.
2. Quantity Demanded: It is the specific amount of a good or service that consumers are willing and able to buy at a particular price. For concert tickets, if the price is set at $50, the quantity demanded might be 5000 tickets.
3. Law of Demand: It states that, ceteris paribus (all other things being equal), as the price of a good or service increases, the quantity demanded decreases, and vice - versa. For fast food, if the price of a burger increases, consumers will generally buy fewer burgers.
4. Elasticity: Elasticity measures the responsiveness of the quantity demanded or supplied of a good to a change in one of its determinants (such as price, income, or price of related goods). For designer clothing, since it is a luxury item, its demand is likely to be elastic. A change in price will lead to a relatively large change in the quantity demanded.
5. Elastic (Elastic Demand): Elastic demand occurs when the percentage change in quantity demanded is greater than the percentage change in price. For movie ticket prices, if the price of tickets increases by 10% and the quantity demanded decreases by 20%, the demand for movie tickets is elastic.
