What is the difference between the supply and the quantity supplied of a product, say milk? Explain in words and show the difference on a graph with the supply curve for milk.

Supply is the total amount of a product that producers are willing and able to sell at each possible price level, given factors like production costs, market conditions, and other external factors. Quantity supplied refers to the amount of a specific product (or good) that producers are willing and able to sell at a specific price. So, the supply is a broader concept that represents the relationship between price and quantity, while the quantity supplied is a single point on the supply curve that corresponds to a specific price.

The supply curve is a graphic representation of the relationship between the price of a product and the quantity of that product producers are willing to supply. Generally, this curve is upward-sloping, which indicates that as the price of the product increases, the quantity supplied also increases. The supply curve can help us better understand the difference between supply and quantity supplied.

To create the supply curve for milk, we need two axes - the x-axis, representing the quantity of milk supplied, and the y-axis, representing the price of milk. We can assume an upward-sloping curve, as higher prices incentivize producers to supply more milk to the market due to higher potential profits.

To illustrate the difference between supply and quantity supplied on the graph, we can look at two distinct points on the supply curve. For example, let's consider Point A and Point B on the supply curve. At Point A, let's say the price of milk is \(P_A\) dollars per gallon, and the quantity supplied is \(Q_A\) gallons of milk. This point represents a specific quantity of milk supplied (quantity supplied) when the price is equal to \(P_A\). At Point B, let's say the price of milk is \(P_B\) dollars per gallon, and the quantity supplied is \(Q_B\) gallons of milk. This point represents another specific quantity of milk supplied (quantity supplied) when the price is equal to \(P_B\). The supply curve represents the overall supply for milk at each price level, showing a positive relationship between price and quantity supplied. Instead of focusing on just one point, the supply curve considers the entire range of prices and their corresponding quantities supplied in the context of milk production.
