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
