Supply chain as connected supply and demand curves. In microeconomics, supply and demand is an economic model of price determination in a market.It postulates that, holding all else equal, the unit price for a particular good or other traded item in a perfectly competitive market, will vary until it settles at the market-clearing price, where the quantity demanded equals the quantity supplied ...
A supply is a good or service that producers are willing to provide. The law of supply determines the quantity of supply at a given price. [5]The law of supply and demand states that, for a given product, if the quantity demanded exceeds the quantity supplied, then the price increases, which decreases the demand (law of demand) and increases the supply (law of supply)—and vice versa—until ...
Supply is often plotted graphically as a supply curve, with the price per unit on the vertical axis and quantity supplied as a function of price on the horizontal axis. This reversal of the usual position of the dependent variable and the independent variable is an unfortunate but standard convention.
Both firms produce a homogenous product: given the total amount supplied by the two firms, the (single) industry price is determined using the demand curve. This determines the revenues of each firm (the industry price times the quantity supplied by the firm). The profit of each firm is then this revenue minus the cost of producing the output.
Reduction in price increases the quantity demanded, but reduces payments by those who would be willing to pay a higher price: MR < P. Marginal cost (MC) relates to the firm's technical cost structure within production, and indicates the rise in total cost that must occur for an additional unit to be supplied to the market by the firm.

This is useful because economists typically place price (P) on the vertical axis and quantity (demand, Q) on the horizontal axis in supply-and-demand diagrams, so it is the inverse demand function that depicts the graphed demand curve in the way the reader expects to see.
When price goes up, quantity will go down. Whether the total revenue will grow or drop depends on the original price and quantity and the slope of the demand curve. For example, total revenue will rise due to an increase in quantity if the percentage increase in quantity is larger than the percentage decrease in price.
The price of a product or service is defined as cost plus profit, whereas cost can be broken down further into direct cost and indirect cost. [1] As a business has virtually no influence on indirect cost, a cost reduction oriented cost breakdown analysis focuses rather on factors contributing to direct cost.
