Task: Write a query that returns one row per rider city, with the total fare taken from that city's riders on rides that actually happened — status is 'completed' — as total_fare. Arrange the cities alphabetically.
Example output — shape only, on invented cities and takings. A total that lands on a whole dollar prints as 41, not 41.0.
| city | total_fare |
|---|---|
| Boise | 88.5 |
| Reno | 41 |
| Tulsa | 120.25 |
