Answer:
The difference between price elasticity of demand and income elasticity of demand is that income elasticity of demand examines how an​ individual's income changes when prices change and the price elasticity of demand examines how quantity demand changes when price changes.
Income elasticity of demand is the measures of the demand of a good or a service in response to the change in income. Whereas the price elasticity of demand refers to the change in the desire to buy a product with an increase in its price.
