2.    
(Ignore income taxes in this problem.) Five years ago, the City of Paranoya spent

$30,000

to purchase a computerized radar system called W.A.S.T.E. (Watching Aliens Sent To Earth). Recently, a sales rep from W.A.S.T.E. Radar Company told the city manager about a new and improved radar system that can be purchased for

$50,000

. The rep also told the manager that the company would give the city

$10,000

in trade on the old system. The new system will last 10 years. The old system will also last that long but only if a

$4,000

upgrade is done in 5 years. The manager assembled the following information to use in the decision regarding which system is more desirable:

 

$30,000$50,000

$10,000-
