How does the quantity demanded respond to a change in price?
Price elasticity of demand demonstrates how a change in price affects the quantity demanded. It is computed as the percentage change in quantity demanded over the percentage change in price, and it will commonly result in a negative elasticity because of the law of demand.

What a buyer pays for a unit of the specific good or service is called price. The total number of units purchased at that price is called the quantity demanded. A rise in price of a good or service almost always decreases the quantity demanded of that good or service. Conversely, a fall in price will increase the quantity demanded.
When quantity demanded decreases in response to?
When quantity demanded decreases in response to an increase in price? This option is correct because when quantity demanded decreases in response to a change in price, there is an upward movement in the demand curve. It means as price rises, leading to a reduction in the quantity demanded, there is upward movement.

What is quantity demanded?
Quantity demanded describes the total amount of goods or services demanded at any given point in time, depending on the price being charged for them in the marketplace.
How does a change in quantity demand occur?
Thus, a change in quantity demanded is a change in quantities purchased due to the increase or decrease in price. The change in quantity demanded is measured using the movement along the supply curve. It is critical to note that a change in quantity demanded only occurs when other factors other than price are kept constant. For instance, an increase in bread price would lead to less demand for bread, hence increasing quantities demanded. Further, a decrease in bread’s price would lead to more demand, leading to a downwards movement in the demand curve.
How does a change in demand affect a product?
A change in demand increases or decreases in a good’s demand due to the change in various demand determinants. A shift in the demand curve measures a change in demand. The shift in the entire demand curve is due to a change in customer preferences, substitutes and complements population, expectations, and incomes. A shift in the demand curve only occurs when the price is constant. Thus, an increase in demand is simply a rise in a product’s demand at a given price. A good example of a change in demand is analyzing the purchase of essential products. For instance, the quantity of salt demanded would remain constant or equal, despite price changes. Therefore, a reduction or increase in the price of salt would not affect its consumption.
