 Subscribers/Group  | 
 Cost/Group  | 
| 
 A  |

The company has set a budget of $25,000 for advertising and wants to maximize the number of subscribers exposed to their ads. However, publishers B and D are competitors and only one of these may be chosen. A similar situation exists with publishers C and G.
Formulate and solve an integer optimization model to determine which publishers to select and how many groups to purchase for each publisher.
