What Is Supply and Demand


There is a difference between supply and demand. Supply means how much of something stores or companies are willing to sell to the people. Demand just means how much of something people are able to buy. Something that I found that was interesting from a quiz that I took was that a lot of things are made out of oil. I was surprised to know that many of the things that I own and use are made out of oil. I would be horrible if we would ever run out of oil
