Marginal Revenue is the derivate (rate of change) of total revenue. Total revenue is = Price x Quantity. For instance, if the demand curve was Q = 100 - P, find the inverse demand (P = 100 - Q). Total Revenue = 100Q-Q^2
Therefore marginal revenue is the derivative of 100Q - Q^2.
MR = 100 - 2Q (thus twice the negative slope).
In short: inverse demand x Q, find the derivative.
explain graphically the movement along the demand curve
show how the price elasticity of demand is graphically measured along a liner demand curve?
Firms in most cases opt to select prices in the elastic regions of their demand curve. This fact explains why marginal revenue curve is always below.
the market demand is curved from the top left to the bottom right hand side corner.
explain what happens inside curve sample
Because in Economics, the demand curve always goes down. It's always changing because or suppy and demand.
The principle of diminishing marginal utility explains the slope of the demand curve by letting us be able to see which direction the slope is in, which is always downward.
explain why the price elasticity of demand varies along a demand curve, even if the demand curve is linear.
price elasticities are always negative hence brings ambiguities in the demand curve
A perfectly inelastic demand curve will be completely horizontal and means that consumers would any price for a particular good, which is almost impossible. The closer to being horizontal a demand curve is, the more inelastic the demand.
because demand decreases as price increases :)
marginal revenue always lies behind the demand curve,and when demand increases marginal revenue also increases.demand curve is used to determine price of a commodity.
