Questions students ask

How do you calculate price elasticity of demand?

PED = % change in quantity demanded / % change in price, or (ΔQ/ΔP) × (P/Q) at a point.

When does raising the price increase revenue?

When demand is price inelastic (|PED| < 1): quantity falls by a smaller percentage than the price rises.
