A medium-sized industrial grade compressor can be purchased for$35,000. Annual O&M costs are expected to increase $1,300 everyyear, with a 1st year O&M cost of $2,000. (MARR =16%, andplanning horizon is 10 years)
• The compressor salvage value for a given period t, iscalculated based on the following equation: Salvage value (t) =$30,000– $3,000 * t
