If the price elasticity of demand (PED) of petrol is less than 1, if the price increases by 10% how will the demand change? Thus, will the revenue of the company increase or decrease?
Since the PED is less than 1, a percentage increase in price will result in a smaller percentage decrease in quantity demanded. In other words, petrol is a necessity and although prices increase by 10%, demand should fall by less than 10% as people will use it despite the higher price. Thus, the revenue of the company selling petrol is unlikely to fall.
