Four mutually exclusive projects are being considered for a new two-mile jogging track. The life of the track is expected to be 80 years, and the sponsoring agency's MARR is 10 % per year. Annual benefits to the public have been estimated by an advisory committee and are shown below. Use the IRR method (incrementally) to select the best jogging track. (Hint: DN indicates "do nothing" alternative).

B Initial cost Annual benefits Rate of return on investment $62,000 $10,000 16.1% $52,000 $8,000 15.4% $150,000 $20,000 13.3% $55,000 $9,000 16.4% First, check AC The i' is %, so select (Round to one decimal place.) Then check AC The i' is %, so select (Round to one decimal place.) Next check AC The 7' is 1%, so select (Round to one decimal place.) Finally, check Ad The i' is %, so select (Round to one decimal place.) Therefore, the best jogging track is
