Elastic
The quantity is decreasing.
Multiplying
If the percent of change is negative, then it is wrong.
By two amounts of change I assume mean absolute amounts. Assume the following: Quantity 1 begins at 6 and changes to 3. The absolute value of the change is 3 and the percent change is 50% Quantity 2 begins at 30 and changes to 27. The absolute value of the change is 3 and the percent change is 10%
Constant is a quantity that does not change.
in equilibrium
Unit elastic
When the percentage change in price is equal to the percentage change in quantity demanded then demand is said to be unit elastic. There are 3 kinds of price elasticity of demand.
a change in demand is a movement along the demand curve, and a change in quantity demanded is a shift in the demand curve
The percentage change is always 100*(new-old)/old provided the old is non-negative. If the original quantity is greater than the new quantity, the percentage change will be negative - no big deal.
This is called equilibrium.
To calculate the quantity demanded when the elasticity is given, you can use the formula: Quantity Demanded (Elasticity / (1 Elasticity)) (Price / Price Elasticity). This formula helps determine the change in quantity demanded based on the given elasticity and price.
it means that price is elastic. Price elastic means that a little change in the price will cause a substantial change in the quantity demanded.
The response of the quantity demanded with a change in price.
Price elasticity of demand is the responsiveness of quantity demanded of a good to a change in its price.Basically it describes how consumers react to a price change.The price elasticity of demand is calculated byPED= %Quantity demanded : % Change of Priceor in words: the percentage change in the quantity demanded divided by the percentage change in price
inelastic
it refers to the the responsiveness of quantity of goods demanded by consumers when there is a change in price level. The formula PED is percentage change in quantity demanded divided by percentage change in price of that particular good.
