Demand is:
1. how many of a product or service people wish
to buy.
2. the people must be able to buy the thing.

Price Elasticity of demand
A Co will want to know how their customers
will react to a change in price.
Elasticity means how much or how little
change happens when price goes up or down.

Elasticity of demand Elasticity of Demand =
_% in Quantity Demanded % in Price
= Change
= (Q2 Q1) X 100 Q= Quantity(how many)
(P2 P1) X 100 P= Price
Old price 24 new price 20
Demand =30 New Demand 50

Example of elasticity
_% in Quantity Demanded % in Price
= (Q2 Q1) X 100
(P2 P1) X 100
(50 30)*100
(24 20)*100
Elasticity= 500%
This product is very elastic!

Meaning of elasticity
% is >1 Product is very elastic
This means a small change in price will lead to
a bigger change in demand.
Any price increase, will really hurt the Co
A price decrease will really help the Co.

% is =1
This is called unit elasticity.
The demand the same as the price change.

Factors affecting elasticity of demand
1. Income elasticity.
This is a measure of how elastic/inelastic achange in income is to demand.
That is if the person is getting more will he buymore
Or if the person is getting more money will hebuy the same or a little more.

Formula for Income Elasticity of demand
% in Quantity Demanded
% in Income
e.g. (45 40)*100____(3500 -3500)* 100
= 0.01 = 10%
The income elasticity is inelastic!

Meaning of Income Elasticity
% is >1 = Very elastic
A small change in income will have a bigeffect on Sales.
If income is elastic.
This means if people get more mony they willbuy more

This means if one products price affects the
price of another.

Examples of cross price elasticity
If the % is >1 Then a small change in the price of one will
affect the other
E.g. Butter and margarine.
If the % is
