Sorting list where the second "column"comes first

I’m stuck with this exercise, where the task is “Sort medical_records so that the individuals with the lowest insurance costs appear at the start of the list.”

[(‘Aaron’, 7640.0), (‘Emily’, 6072.0), (‘Jide’, 5360.0), (‘Mohamed’, 13262.0), (‘Nikita’, 2750.0), (‘Paul’, 5054.0), (‘Paul’, 12064.0), (‘Priscilla’, 8320.0), (‘Sara’, 4816.0), (‘Valentina’, 14724.0), (‘Xia’, 6839.0)]
