The degree of responsiveness of change in demand as a result of change in its price is known as elasticity of demand. I mathematical language we can say that;
Elasticity of demand =
%age change in Quantity Demanded
DIVIDED BY
%age change in the Price.
it is what elasticity of demand
price elasticity of demand is the degree of responsiveness of demand where by change in price of a commodity bring proportionate change in quantity demanded.
Price elasticity of demand is a way to determine marginal revenue. Optimal revenue and, more importantly, optimal profit will occur to the point when marginal revenue = marginal cost, or the price elasticity of demand < 1.
When you have less income you tend to consume less.

The concept of elasticity of demand was primarily evolved by economists Alfred Marshall and Arthur Cecil Pigou. Marshall introduced the idea in his seminal work "Principles of Economics" in the late 19th century, where he defined elasticity as a measure of how quantity demanded responds to price changes. Pigou later refined the concept, helping to establish it as a fundamental principle in microeconomic theory.
Unitary elasticity is when the price elasticity of demand is exactly equal to one.
distinguish between price elasticity of demand and income elasticity of demand
Cross elasticity of demand measures the responsiveness of the quantity demanded for one good to a change in the price of another good. It is calculated as the percentage change in quantity demanded of Good A divided by the percentage change in price of Good B. A positive cross elasticity indicates that the goods are substitutes, while a negative cross elasticity suggests they are complements. This concept helps businesses understand how changes in pricing strategies can affect demand for related products.
Elasticity, in economic terms, refers to the responsiveness of one variable to changes in another variable, typically used to measure how the quantity demanded or supplied of a good responds to changes in price. The concept was developed in the 19th century, with significant contributions from economists like Alfred Marshall, who formalized the concept in his work on supply and demand. Elasticity can be categorized into different types, such as price elasticity of demand, income elasticity, and cross-price elasticity, each providing insights into consumer behavior and market dynamics.
I am at a loss for the answer please help me.
there are three methods of measuring elasticity of demand
