Supply and demand is perhaps one of the most basic concepts of economics and it is the backbone of a market economy. Demand refers to how much of a product or service is desired by buyers. The quantity demanded is the amount of a product people are willing to buy at a certain price; the relationship between price and quantity demanded is known as the demand relationship. Supply represents how much the market can offer. The quantity supplied refers to the amount of a certain goods producers are willing to supply when receiving a certain price. The relationship between price and how much of a goods or service is supplied to the market is known as the supply relationship. Price, therefore, is a reflection of supply and demand.
The law of demand states that, if all other factors remain equal, the higher the price of a product, the fewer people will demand that product. The amount of goods that buyers purchase at a higher price is less as the price of a product goes up, so does the opportunity cost of buying that product.
Like the law of demand, the law of supply shows the quantities that will be sold at a certain price. But unlike the law of demand, the supply relationship shows an upward slope. This means that the higher the price, the higher the quantity supplied. Producers supply more at a higher price because selling a higher quantity at a higher price increases the whole income.
Now that we know the laws of supply and demand, let’s turn to an example to show how supply and demand affect price.
Imagine that a CD of your favorite band is sold for $20. Because the record company’s previous analysis showed that consumers will not demand CDs at a price higher than $20, only ten CDs were sold because the opportunity cost is too high for suppliers to produce more. If, however, the ten CDs are demanded by 20 people, the price will then rise. As a result, the rise in price should cause 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 is more than the demand.

Signs can sometimes be seen at the entrance of a house, expressing that a tramp has passed. This special sign-language is frequently 36 by tramps to inform their 37 whether the host of a certain house is friendly or unfriendly, and to 38 them the trouble of making unnecessary calls.
Quite 39 one day, I came across a real tramp. He was such a rare sight these days that I stood some distance away and watched him. He was dressed just as a tramp should be 40 , old worn trousers, and a jacket many sizes too big for him. On his head there was a battered old hat and his boots were so old and worn; they were almost coming into 41 . But the man himself looked cheerful as if he had not a 42 in the world. He rubbed his nose with his forefinger, 43 a funny turn, laid a small parcel by the front gate, and began 44 a sign made by a former caller. Although the sign was meaningless to me, it must have been 45 , for the tramp’s face lit up with 46 . He entered the front gate confidently and rang the bell. When the door opened, I saw him 47 his hat but couldn’t hear his words. The 48 was very short indeed, for no sooner had he spoken a few words than the door closed fiercely in his face. I felt 49 for him as he walked 50 out of the house, But just as quickly, his face lit up again and he moved quickly towards the gate. There he stopped, looked at the sign, and 51 his head seriously as if he had made a bad mistake. 52 deeply into his pockets, he produced a piece of chalk, rubbed out the 53 sign and made a new one in its place. He stared at it for a moment smiling to himself, then gathered his 54 , pushed back his hat and began walking towards the next house at an unhurried 55 , whistling as he went along.
