The concept of supply and demand is used often in business. In general, as the unit price of a commodity increases, the demand for that commodity decreases. Also, as a commodity's unit price increases, the manufacturer normally increases the supply. The point where supply is equal to demand is called the equilibrium point. The following shows the graph of a demand equation and the graph of a supply equation for previously rented DVDs. The $x$ -axis represents the number of DVDs in thousands, and the $y$ -axis represents the cost of a DVD. Use this graph to answer Exercises 79 through 82. (GRAPH CANNOT COPY). When $x$ is between 3 and $4,$ is supply greater than demand or is demand greater than supply?

Key Concepts

Graphical Analysis in Economics

Graphical analysis in economics involves using visual representations, such as supply and demand curves, to illustrate the relationship between price and quantity. Graphs help in identifying critical points like the equilibrium point, and in analyzing how shifts in supply or demand can affect market dynamics.

Market Equilibrium

Market equilibrium occurs at the point where the quantity supplied equals the quantity demanded. At this equilibrium point, the market is in balance, meaning there is neither a surplus nor a shortage, and the prevailing price stabilizes the interactions between consumers and producers.

Supply

Supply refers to the quantity of a commodity that producers are willing and able to offer for sale at various price levels. Generally, as the price increases, producers are incentivized to supply more of the commodity due to the prospect of higher revenue, reflecting the direct relationship between price and quantity supplied.

Demand

Demand is the quantity of a commodity that consumers are willing and able to purchase at different price levels. Typically, as the price of a commodity increases, the quantity demanded decreases since consumers tend to buy less when the commodity becomes more expensive, illustrating the inverse relationship between price and quantity demanded.
