D D1. Also Read Break-even Point: Meaning, Advantages, Disadvantages and Examples In economics, the equilibrium price represents the price that if practiced on the market will result in the fact that the whole quantity that is supplied is presumably sold, meaning that on the market the economic forces named generally as the supply and demand are balanced and that there are no external influences that may have an impact on the price mechanism. To do this, we will follow a simple 4-step process: (1) draw the supply and demand curves, (2) find the market price, (3) connect the price axis and the market equilibrium, and (4) calculate the area of the lower triangle. The graph is calculated using a linear function that is defined as P = a - bQ, where "P" equals the price of the product, "Q" equals the quantity demanded of the product, and "a" is equivalent to non-price factors that affect the demand of the product.
