Answer:
Price elasticity of demand = Change in Quantity/ Change in Price
Using midpoint formula;
Change in Quantity ;
[tex]= \frac{Q2 - Q1}{\frac{Q1 + Q2}{2} } \\\\= \frac{363 - 513}{\frac{513 + 363}{2} }\\\\= -0.342[/tex]
Change in Price;
[tex]= \frac{P2 - P1}{\frac{P1 + P2}{2} } \\\\= \frac{0.99 - 0.88}{\frac{0.99 + 0.88}{2} }\\\\= 0.118[/tex]
Price elasticity of demand = -0.342/0.118
= -2.90
Demand is elastic, so decreasing ticket prices will increase revenue.
When the elasticity is larger than 1 it means that a 1% change in price will change demand by more than 1%. In this case, a a decrease of price by 1% will bring 2.9% increase in customers.
