1. The net present value of Alternative 1 is $90,755.
2. The net present value of Alternative 2 is $14,355 with the sale proceeds of the old machine.
3. Based on the net present value, Interstate Manufacturing should <em>overhaul the old machine instead of replacing it with the new one.</em>
Data and Calculations:
Required rate of return = 10%
Alternative 1 Alternative 2
Cost of old machine $111,000 ($29,000)
Cost of overhaul 158,000 $300,000
Expected annual revenues 106,000 94,000
Expected annual operating costs 43,000 22,000
Net cash flows for 5 yrs 63,000 72,000
Salvage value after 5 yrs 16,000 20,000
PV annuity factor of 10% for 5 years = 3.7908
PV factor of 10% for 5 years = 0.6209
Alternative 1 Alternative 2
PV value of annual net cash flows 238,820 272,937
PV value of Salvage value 9,935 12,418
Present value of cash inflows $248,755 $285,355
Cost of overhaul/Investment (158,000) (300,000)
Proceeds from the sale of old machine 29,000
Net present value $90,755 $14,355
Thus, based solely on the net present values of alternatives 1 and 2, Interstate Manufacturing should <em>overhaul the old machine</em> (alternative 1) because it yields a greater net present value than alternative 2.
