the demand curve to a change in income.

A demand curve is a graphic that shows the relationship between the amount of money people are willing to spend on a product and the amount of money they would spend on it if they had more money. The idea is that demand curves show how the amount of money people are willing to spend on a product depends on how much money they have. For example, if the price of a car drops, it becomes harder to buy a car.

In the case of the demand curve, there’s a little catch in that the more money people are willing to spend on a product, the more people will be willing to spend on it. This is because people are more willing to spend money if they feel they have more money. For example, in the case of a new car, if demand is high, then more people will be willing to buy the new car.

But since there is a catch in the demand curve, the actual price of a product will be unaffected by demand. But this doesn’t mean the price of a car is going to be at its lowest. There is a price elasticity to demand where the cheaper you make a product, the more it will sell. At the same time, demand is not dependent on the actual price. In fact, you can increase the price of a product, and still make it sell.
