#### Solution Preview

6. Proportionality

7. a.

The constraint should have inequality and right hand side value.

8. d.

Proportionality - The contribution of each activity to the value of the objective function and the "left hand side" of each constraint is proportional to the level of the activity (value of the decision ...
