c = T/f + n/4 = 5/4 + 3/4 = 8/4 = 2

Hi guerrero,

This question is essentially a "symbolism" question (albeit with an equation instead of a symbol): you're told what each variable in the equation "means" and then we're asked to do a simple calculation using data from a table:

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

Final Answer: D
