Question 484561: 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.

You can put this solution on YOUR website!
16.3=0.11(x-1980)+14.1
2.2=.11(x-1980)
2.2/.11=x-1980
20=x-1980
2000=x
After 2000, a 65-year old man can expect to live at least 16.3 years longer..
