A remotely located air sampling station can be powered by solar cells or by running an above ground electric line to the site and using conventional power. Solar cells will cost $17,400 to install and will have a useful life of 5 years with no salvage value. Annual costs for inspection, cleaning, and other maintenance issues are expected to be $2,100. A new power line will cost $26,000 to install, with power costs expected to be $1,000 per year. Since the air sampling project will end in 5 years, the salvage value of the line is considered to be zero. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. At an interest rate of 10% per year and using an AW analysis, which alternative should be selected? The annual worth of installing solar cells is $− , and the annual worth of installing a new power line is $− . The alternative to be selected is
