Compare the two scenarios for acquiring a machine for a project for 22 years expected operations, at a company with an internal rate of return of i = 16%. Using PW, find which scenario is better.

Scenario

1. Buy an initial small machine at $13,000, it cost $2,400/year to run for the first 12 years, buy a second larger machine at $26,000 and run it for 10 years at a cost of $4,000/year. There is no salvage value at the end of service for either machine. Scenario

2. Buy a large machine for $36,000 and run it for 22 years at a cost of $1,000/year. At the end of the 22 years, the machine is assumed to have a salvage value of $5,000.
