THE ELASTICITY OF DEMAND
Price elasticity of demand is a measure of how much the quantity demanded of a good responds to a change in the price of that good.
Price elasticity of demand is the percentage change in quantity demanded given a percent change in the price.

The Price Elasticity of Demand and Its Determinants
Demand tends to be more elastic :
the larger the number of close substitutes.
if the good is a luxury.
the more narrowly defined the market.
the longer the time period.

The Midpoint Method: A Better Way to Calculate Percentage Changes and Elasticities
The midpoint formula is preferable when calculating the price elasticity of demand because it gives the same answer regardless of the direction of the change.

The Variety of Demand Curves
Because the price elasticity of demand measures how much quantity demanded responds to the price, it is closely related to the slope of the demand curve.

Summary
Price elasticity of demand measures how much the quantity demanded responds to changes in the price. 
Price elasticity of demand is calculated as the percentage change in quantity demanded divided by the percentage change in price.
If a demand curve is elastic, total revenue falls when the price rises. 
If it is inelastic, total revenue rises as the price rises.
