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.
Unit elastic
a change in demand is a movement along the demand curve, and a change in quantity demanded is a shift in the demand curve
Price elasticity of demand= percentage change in demand/percentage cgange in price 2 = % chnge in demand/10 % change in demand= 2*10 % change in demand= 20%
A change in quantity demanded
The response of the quantity demanded with a change in price.

A change in 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
A change in quantity demanded refers to the response of consumers to changes in the PRICES of commodities, ceteris paribus.>> Involves a movement along the demand curve A change in demand refers to an increase or decrease in demand brought about by a change in the conditions of non-price determinants.>> Involves a shift in the demand curve (to the left or right)
Decrease in quantity demanded usually results from an increase in price and vice versa. When the price of a product increases, the demand curve itself is not affected. However, the quantity demanded decreases to a higher point along the demand curve.
Elasticity of demand is the responsiveness of quantity demanded of a good or service to changes in the price. Elastic demand means that for a change in price, the change in quantity demanded is more than proportionate. So the cheaper the price gets (say 1 unit), the quantity demanded will increase improportionately (say 2 units).
by the formula : %changge in quantity demanded/% change in price of good
