  1. 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
