This measures how much the quantity supplied of a good changes in response to a change in the price of that good.

Midpoint Formula

A method used in economics to calculate the elasticity of a variable, such as demand or supply, based on changes in price and quantity from a midpoint on a curve.

Elastic

Describes a situation in economics where the demand or supply for a good or service significantly changes in response to a change in price.
