Question

Machines that have the following costs are under consideration for a robotized assembly process. Using an interest rate of 6% per year, determine which alternative should be chosen on the basis of a present worth analysis:

Machine A

Machine B

First cost ($)

200,000

150,000

Annual operating costs ($/yr)

50,000

60,000

Salvage value ($)

30,000

Explanation / Answer

Consider first Machine A

Present worth of machine An

PWA =-200000-50000(P|A, 0.06,2)+30000(P|F, 0.06,2)

=-200000-500000(1.834)+30000(0.8899)

=-265003

Now consider Machin B

PWB =-150000-60000(P|A, 0.06,3)+20000(P|F, 0.06,3)

=-150000-60000(16.66)+20000(0.839)

=-1132820

Therefore PWA>PWB

Hence chose machine A
