How do you get +150% experience tickets?

When you get tickets in Salmon Run you'll most likely get the +100% and +150% experience tickets in a super bonus, not a regular bonus. You'll need to play quite a bit of Salmon Run to get it because you need to get 600p to get it, and even then, there's only a 50% chance you'll get a ticket.

You can also get them though Octo-Expansion. When you beat Octo-Expansion, There will be a vending machine in Central Station. By using 15000 points, you can get items including 50%, 100% and 150% tickets.
