Answer 1

Answer:

1. 76.7 million
2. 89.1 million
3. 75 million

Step-by-step explanation:

Let x represent the arrivals and departures at the third airport. Then the number at the first airport is x+1.7, and the number at the second airport is x+14.1. The total is ...

  (x+1.7) + (x+14.1) + (x) = 240.8

  3x +15.8 = 240.8

  3x = 225

  x = 75

  x+1.7 = 76.7

  x+14.1 = 89.1

The first airport has 76.7 million arrivals.

The second airport has 89.1 million arrivals.

The third airport has 75 million arrivals.
