A remotely located air sampling station can be powered by solar cells or by running an electric line to the site and using conventional power. Solar cells will cost \( \$ 19,000 \) to install and will have a useful life of 4 years with no salvage value. Annual costs for inspection, cleaning, etc. are expected to be \( \$ 1,100 \). \( A \) new power line will cost \( \$ 9,000 \) to install, with power costs expected to be \( \$ 800 \) per year. Since the air sampling project will end in 4 years, the salvage value of the line is considered to be zero. At an interest rate of \( 14 \% \) per year, which alternative should be selected on the basis of a future worth analysis? The future worth of solar cells is \( \$ \) \( \boldsymbol{x} \) and that of electric line is \( \$ \) \( \boldsymbol{x} \). should be selected on the basis of a future worth analysis.
