Presets

Elasticity measures how much quantity demanded responds to price. Where demand is elastic (|E| > 1), a price cut raises total revenue; where it is inelastic, a price cut lowers revenue. On a straight-line demand curve the top half is elastic, the bottom half inelastic, and revenue peaks exactly at the midpoint where elasticity equals one.

Governing equation

Reading this result: You are at the unit-elastic midpoint: revenue is at its maximum, and small price moves in either direction leave it roughly unchanged.
