price elasticity of demand equation
percentage change in quantity demanded ÷ percentage change in price
understanding the answer - ELASTIC
any price change causes a larger change in demand
value of -1 or lower
understanding the answer - UNITARY ELASTIC
demand changes by the same percentage as the price
value of -1
understanding the answer - INELASTIC
demand changes by a smaller percentage than price
value between 0 and -1
