The Athlete's Shop has evaluated two proposals for weight lifting and exercise equipment. A present worth analysis at i = 15% per year of estimated revenues and costs resulted in PWA = $440,000 and PW B = $390,000. In addition to this economic measure, three more attributes were independently assigned a relative importance score from 0 to 100 by the shop manager and the lead trainer.

Separately, you have used the four attributes to rate the two equipment proposals on a scale of 0 to 1.0 as shown in the following table. The economic attribute was rated using the PW values.

Select the better proposal using each of the following methods.
(a) Present worth
