Elastic- when the own-price elasticity is greater than 1 Unit-elastic- when the elasticity is equal to 1 Inelastic- the elasticity is less than 1 The total revenue that a business firm gets from selling a product is the amount of money the firm receives from its sales. TR= (P)(Q) Perfectly elastic- the demand curve is completely horizontal Perfectly inelastic-quantity demanded does not change at all when price changes. The demand curve is a vertical line.
