Question

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 $105,000 and a useful life of 15 years. At the end of its useful life, the punch has no salvage value. Labor costs would increase $3,200 per year using the gang punch, but raw material costs would decrease $12,250 per year. MARR is 5%/year. a)What is the present worth of this investment?
b)What is the decision rule for judging the attractiveness of investments based on present worth?

c)Should Bailey buy the gang punch?

Answer 1

Answer:

a) Present value of the investment: $198,936

b) if the present worth of the investment which are discounted at MARR rate is positive, the investment is worth investing, while if the present value of the investment is negative, Investor should not invest.

c) As calculated in (a), present value of the investment is $198,936, Bailey should buy the gang punch

Explanation:

Please find detailed of calculation in (a) which is shown as below:

Present value =  Present value of saving in raw material - Present value of increase in labor cost - Initial investment = [ (12,250/ 5%) x (1-1.05^-15)] -  [ (3,200/ 5%) x (1-1.05^-15)] - 105,000 = $198,936.
