Step-by-step explanation:
To express the relative change between the number of scheduled passenger flights in September 1995 and September of last year, we can use the percentage change formula.
Percentage Change = (New Value - Old Value) / Old Value * 100

Percentage Change = (753,328 - 734,260) / 734,260 * 100 = 2.60%
Therefore, the relative change in the number of scheduled passenger flights between September 1995 and September of last year is approximately 2.60%
