Yes this statement is true because of law of demand which explains that " the QUANTITY SUPPLIED DECREASES WITH THE FALL IN PRICE and increases with the rise in price...."
and according to the law of demand,decrease in the price increase the demand......
and when price decreases then supply also decreases.....
HENCE PROVED ...

Introduction:
The statement "An increase in the demand for Notebooks raises the quantity of Notebooks demanded, but not the quantity supplied" is a fundamental concept of microeconomics, which describes the relationship between demand and supply. In this response, we will examine whether this statement is true or false and explain the reasons behind it.

Demand and Supply:
Demand: It refers to the quantity of a good or service that consumers are willing and able to buy at a given price. It is represented by a downward-sloping curve, which shows that as the price of a good or service increases, the quantity demanded decreases, and vice versa.

Supply: It refers to the quantity of a good or service that producers are willing and able to sell at a given price. It is represented by an upward-sloping curve, which shows that as the price of a good or service increases, the quantity supplied also increases, and vice versa.

Explanation:
The statement "An increase in the demand for Notebooks raises the quantity of Notebooks demanded, but not the quantity supplied" is true because of the following reasons:

- When there is an increase in the demand for Notebooks, it means that consumers are willing and able to buy more Notebooks at a given price. This causes an upward pressure on the price of Notebooks, which is represented by a movement along the supply curve.

- However, the supply of Notebooks is determined by the willingness and ability of producers to sell them at a given price. If the price of Notebooks increases, producers are likely to increase the quantity supplied to take advantage of the higher price. But, if the price remains the same, producers will not increase the quantity supplied, as it will not be profitable for them to do so.

- Therefore, an increase in the demand for Notebooks raises the quantity of Notebooks demanded, but not the quantity supplied. This leads to a situation where the demand for Notebooks exceeds the supply, which is represented by a shortage in the market.

- A shortage in the market creates an incentive for producers to increase the quantity supplied, as they can sell more Notebooks at a higher price. This process continues until the market reaches a new equilibrium point, where the quantity demanded equals the quantity supplied.

Conclusion:
In conclusion, the statement "An increase in the demand for Notebooks raises the quantity of Notebooks demanded, but not the quantity supplied" is true. It is important to understand this concept as it helps in analyzing the behavior of markets and the impact of changes in demand and supply on prices and quantities.
