Answer:
4, 1, 2,
Step-by-step explanation:
Here are the projects and their returns
Project Return (%)
1 14
2 12
3 10
4 15
5 12
the firm should choose the project with the highest returns
Projects are mutually exclusive if the projects cannot occur at the same time. If one project is chosen, the others cannot be chosen.
Project 3,4,5 are mutually exclusive. If one of the projects are chosen, other projects cannot be chosen.
Project 4 has the highest return, so it would be chosen first.
the next project with the next highest return is project 1 and then project 2
