If a consumer's income increases and if all goods are normal goods, explain how the quantity bought of each good changes

What will be an ideal response?

If the consumer's income increases and all the goods consumed are normal goods, then the consumption of all goods increase. With the increase in income, the initial consumption possibility is now affordable with money left over. If the consumer's utility for all goods increases with consumption, because the consumer seeks to maximize utility subject to prices and available income, he or she will use the money left over from the initial bundle to increase the quantity consumed for all goods and services. By doing so the consumer increases his or her total utility. This increase occurs while the price of these goods and services remained unchanged, which indicates there is a rightward shift of the demand curve for all goods and services.
