How to unlock the I ran the numbers achievement in Arcade Paradise - Definitive Guide
This isn't directly story related, but will come naturally during progression in the game. You can modify difficulty and play costs for each game but completing goals and keeping the business clean are the biggest money boosts. You'll likely get this achievement sometime between the 3rd and 4th expansion, with approximately 15 cabinets/games active.
This is actually fairly easy once you obtain a decent amount of cabinets. Simply go into the management screen and toggle between difficulty and price to maximize the profit per hour of each machine. I got my arcade profits up to over 5,000 by the end of the game by doing this.
