PRICE ELASCITIY OF DEMAND: There are several uses of Price Elasticity of Demand that is why firms gather information about the Price Elasticity of Demand of its products. A firm will know much more about its internal operations and product costs than it will about its external environment. Therefore‚ gathering data on how consumers respond to changes in price can help reduce risk and uncertainly.

1. Compute the price elasticity of demand between these two points. Let quantity demanded = Q‚ Q1= 400 meals/day‚ and Q2= 450 meals/day Let price = P‚ P1= $20‚ and P2= $18 The change in quantity demanded = Q2-Q1 = 450-400= 50 The change in price = P2-P1= $18-$20= -2 The average in demand = (Q2+Q1)/2= (450+400)/2= 850/2=425 The average in price = (P2+P1)/2 = (18+20)/2 =38/2= 19 The percentage change in quantity demand = change in quantity demanded/the average in quantity demand =50/425 = 0.1174 =
