8 + 7 = 15
Then do:
26 - 15 = 11
Then place 11 over the amount of people:

Answer:
(2000 - 100x)(5 + x)》12000
10000 - 500x + 2000x - 100x²》12000
-100x² + 1500x + 10000》12000
x for max profit:
-200x + 1500 = 0
x = 7.5
Price = 5 + 7.5 = 12.5
Max profit:
(2000 - 100(7.5))(5 + 7.5)
= 1250 × 12.5
= $15625

Step-by-step explanation:
Given that:
2/15 of flights are international
Flightvare equally divided among 4 countries
Total number of flights = 2250
