Businesses are marked on the map with a suitcase. A business is bought with resistance funds (or just normal money in Single Player) by going to that location, pressing 'Y' to open the Main Menu and then the 'Buy' button located bottom-right. Make sure the business and not a local building is showing as the picture, you may need to move away from nearby houses.
