Bailey, Inc., is considering buying a new gang punch that would allow them to produce circuit boards more efficiently. The punch has a first cost of $60,000 and a useful life of 15 years. At the end of its useful life, the punch has no salvage value. Annual labor costs would increase $3,500 using the gang punch, but annual raw material costs would decrease $7,000. MARR is 4.75 %/year.
1.What is the present worth of this investment?
2.What is the decision rule for judging the attractiveness of investments based on present worth?
3.Should Bailey buy the gang punch?
initial cost = 60000
MARR = 4.75%
t = 15 yrs
Annual savings = 7000
Annual cost = 3500
Net annual revenue = 7000 - 3500 = 3500
PW = -60000 + 3500*(P/A, 4.75%,15)
= -60000 + 3500 * 10.55730
= -23049.45
Decision rule : when PW>0, project should be selected
No as PW<0
