Assume the suggestions in (e) are approved. The manager makes another suggestion to the owners of the business. She proposes that her annual salary be reduced to $20 000 but that as an incentive she be paid $8 for every package sold by the business. Should this option be adopted? (In answering this question, assume first that units sold would not be affected by this change. Then consider the possibility that units sold would increase because of the extra motivation given to the manager.)
