Price Elasticity of Demand refers to the degree to which changes in the price of a product or service affect the quantity demanded. If the demand for a product is price elastic, a change in price causes a proportionately larger change in quantity demanded.
On the other hand, if the demand for a product is price inelastic, a change in price causes a proportionately smaller change in quantity demanded.When the price elasticity of demand is 2.0 and a firm raises its price by 10%, the total revenue will fall.
The answer is letter D. The total revenue will fall by 20%. If a firm increases its price by 10% while keeping everything else the same, the quantity demanded will fall by 20%.Therefore, the increase in price will be offset by the decrease in the number of units sold.
