If, however, the ten CDs are demanded by 20 people, the price will subsequently rise because, according to the demand relationship, as demand increases, so does the price. Consequently, the rise in price should prompt more CDs to be supplied as the supply relationship shows that the higher the price, the higher the quantity supplied.


If, however, there are 30 CDs produced and demand is still at 20, the price will

not be pushed up because the supply more than accommodates demand. In fact after the 20 consumers have been satisfied with their CD purchases, the price of the leftover CDs may drop as CD producers attempt to sell the remaining ten

CDs. The lower price will then make the CD more available to people who had previously decided that the opportunity cost of buying the CD at $20 was too
