Demand is often represented by a table or a graph showing price and quantity demanded (as in the figure).

In the short run, say a single year, quantity demanded is largely determined by market price.

What determines quantity demanded of each good by that individual?

In regard to the question "by how much will quantity demanded rise?"

Thus the law of demand merely states the direction in which quantity demanded changes for a given change in price.

In other words, as the price declines the quantity demanded increases.

This higher quantity demanded would cause the demand curve to shift outward to a new position D2.

But a higher consumer price will reduce the quantity demanded.

As the firm reduces price, the quantity demanded for the firm's product is likely to rise.

The quantities demanded from the various provinces gave a vivid picture of their economic potential.
