Question

Because of medical advances and improved health care, people in the U.S can be expected to live longer. From 1980 to 2005, the number of years Y that a 65yr old man could be expected to live beyond 65 (years remaining), can be approximated by
Y=0.11(x-1980)+14.1
where x represents the year. Determine the years when a 65yr old man could be expected to live an additional 16.3 years or more.
