U.S. : 10,000 tickets

Korea: 10,000 tickets

Step-by-step explanation:

1. Set 15x + 20y = 350,000 and x + y = 20,000

2. x + y = 20,000 ---> y = 20,000 - x

3. Plug in y into the 20y ---> 15x + 20(20,000 - x) = 350,000

4. 15x + 400,000 -20x = 350,000

5. -5x = -50,000

6. x = 10,000

7. Plus in x in y = 20,000 -x ---> y = 20,000 - 10,000

8. y = 10,000
