Answer:
The correct answer is C,2.33
Explanation:
The midpoint formula for elasticity of demand is given as :
percentage change in quantity demand/percentage in price
percentage change in quantity demanded is Q2-Q1/(Q2+Q1)/2*100
percentage change in price is P2-P1/(P2+P1)/2*100
P1=$6.5
P2=$5.75
Q1=600
Q2=800
percentage change quantity demanded =(800-600)/(800+600)/2*100
percentage change quantity demanded=28.57142857
Percentage change in price=(5.75-6.5/(5.75+6.5)/2)*100
percentage change in price=12.24489796
midpoint elasticity of demand= 28.57142857 /2.24489796
=2.33
