The demand equation refers to the mathematical expression of the relationship between the quantity demanded and price. The quantity that is demanded is usually denoted by letter Q while the function of the price is usually denoted by letter P.

A certain commodity the supply equation is given S equals 06p plus 08 At a price of 1 there is a demand of 21 units If the demand equation is linear and the market price is 3 find the demand equation?

S=6p+8 Demand at price 3(assuming equilibrium= 6(3)+8=26 at P=3 d=26 s=26 at p=1 d=21 something is wrong here because according to this demand is upward sloping, which means that as p increases, so does demand, which is the opposite of the law of demand.


Does the ceteris paribus assumption affect a demand curve?

It isolates factors and only looks at one cause and effect at a time. This is why the demand curve is a linear equation (straight line). It wouldn't be possible in real life.


What is the function equation of demand?

The demand function relates price and quantity. It tells how many units of a good will be purchased at different prices. In general, at a higher price, less will be purchased. Thus, the graphical representation of the demand function (often referred to as the demand curve) has a negative slope.


What does Talk is cheap supply exceeds demand mean?

Basic Economics lesson. The price of of commodities is based on a relative relationship of supply and demand. P=D/S if you increase supply of a certain commodity, as well as decreasing the demand, the equation shows that the price will fall or that it is a "cheap" commodity. In terms of the saying... Talk isnt worth much because there is usually alot of it, and for the most part, people dont "demand" it... or want it


Write Equations for Supply and Demand Functions?

supply and demand both are the function of price (as law of demand and law of supply stated). also price has positive impact on supply and negative impact on demand.supply=f(p)demand=f(p)so by having the idea of laws of demand and supplydemand equation can be written as:D=a-bp ; a=intercept , b=slopeand supply equation can be written as:S=c+dp ;c=intercept , d=slopethese equations can only be true if all other things remain sameotherwise we have to include others factors causing change in demand and supply.like income,prefferences,taste,advertisement cost,weather etc for demandand price of resourses(land,labor,capital,row meterial),management skill,technology,marketing,production techniques expectations etc for supply

Is it possible to have no constant in demand equation or no Y intercept?

Possible, but unlikely.


What is the purpose of the Law of Demand?

The "law of demand" is part of an economic equation that dictates the overall worth and value of a commodity. When an item is in high demand the price will increase, when the demand for an item decreases so will the price.

How do you solve when market demand is P equals 1200-Q?

You need the supply equation, a cost function of the suppliers or one of those variables. If this is a competitive market, demand=supply so set the equations equal and solve..

I guess it depends on demand and supply! ... simple equation ...More demand, less supply = High Price, and vice verse


Daily life examples about differential equations?

Here are two variablesDemand and Price, whereas Price is Independent variable &Demand is dependent variable, i.e. if price of something changes the demand will also be affected.

Why did schecter discontinue the 006 elite guitar?

not enough people were buying them. the demand was less than the supply. In order to not loose money they needed to reinvent it or drop it. Schecter chose to drop it. Its simple supply and demand equation for all businesses. More Supply + Less Demand= deflation of prices (in the end less money for company) More Demand + Less Supply= inflation of prices (in the end more money for company)
