### Solution

Option D is the correct answer.

### Option Analysis

We’re given the equation: (T/f) + (n/4)

We’re told to calculate (using that equation) for Airline A and Los Angeles. So, we just have to pull data from the table and plug in the numbers:

F = number of flights that Airline A has to Los Angeles

F = 4

n = number of OTHER airlines with at least 1 flight to Los Angles.

n = 3

t = combined flights to Los Angeles from the other airlines

t = 5

Now, plug in: 5/4 + 3/4 = 8/4 = 2.
