Biomet Implants is planning new online patient diagnostics for surgeons while they operate. The new system will cost $300,000 to install in an operating room, $5000 annually for maintenance, and have an expected life of 4 years. The revenue per system is estimated to be $80,000 in year 1 and to increase by $10,000 per year through year 4. Determine if the project is economically justified using PW analysis and an MARR of 10% per year.

A coal-fired plant has upgraded an emission control valve. The modification costs only $8000 and is expected to last 6 years with a $200 salvage value. The maintenance cost is expected to be high at $1700 the first year, increasing by 11% per year thereafter. Determine the present worth of the modification and maintenance cost both by hand calculation using formula and by spreadsheet at an interest rate of 8% per year.
