The current transit fare is $1.75 for the Columbia Pike Corridor. Arlington County is considering raising the fare to $2.00 to help cover the cost of the new BRT service. Arlington County observed that in a similar corridor, increasing the fare by $0.25 resulted in a drop in ridership from 8,000 to 7,200. Using these data, estimate the demand elasticity and answer the following: 1. What does the value mean?
2. What does the sign of the value mean?
3. What would the new ridership be for the BRT service in the corridor?
