A decrease in the price of eggs from $1.50 to $1.30 per dozen resulted in an increase in egg purchases from 60 to 100. The price elasticity of demand using the midpoint formula is therefore

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
