Answer:
Explanation:
In using the midpoint method to calculate price elasticity , the average percentage change in the price and quantity are used
formula = percentage change in quantity = (Q2 -Q1/(Q2+Q1)/2)*100
Percentage change in price = ( P2 -P2/(P2-P1)/2)*100
Price changes = $1.5 to $1.3
Quantity changes = 60 to 100
Percentage in price = (1.3-1.5 /(1.5+1.3)/2 )*100
(-0.2/1.4)*100 =-14.29%
Percentage in quantity = (100-60/(100+60)/2)*100
40/80*100 = 50%
Therefore , price elasticity of demand = 50/-14.29 = -3.5
With the elastic interval being less than 1 , it means that it is an inelastic demand
