Installing low thermal emissivity windows (low-e windows) on buildings can contribute to energy conservation, Installing lowe windows on a school building is estimated to cost $10,000. The windows are expected to last 6 years and have no salvage value at that time. The energy savings from the windows are expected to be \$2,525 in the 1st year. After the 1st year, the savings are expected to increase by $125 each year due to escalating fossil fuel costs. MARR is 15% per year and annual worth is the preferred measure of economic worth. Which Excel\$ entry should you use to determine the annual worth of installing the low- windows?
