Verified step by step guidance

1. Understand that in economics, demand is not just about wanting a good or service, but also involves the ability and willingness to pay for it.
2. Recognize that demand refers to the relationship between the price of a good and the quantity that consumers are willing and able to purchase at that price.
3. Distinguish demand from supply, where supply is the amount of goods sellers are willing to offer at various prices.
