Pactors affecting Demand

There are 6 factors

affecting demand:

1. Price of the good

Normally, when the

price of the good- decreases, people are

willing and able to buy more, Converselyi vhen the price rises, guy Les. Price of the related good

Tf the two goods are substitutes (***). i.e goods that can easily replace each other, a rise in the price of one good will raise the demand for another. But if they

are complements (租物 e), the goods

Together, a rise in the price of one good will decrease, the demand for pnother

5. Consumers' incume.
