Question 771328: The number of years a person born in the United States is expected to live can be approximated by the equation y=0.189x+70.8, where x is the number of years since 1970. Solve this equation for x. Use this new equation to determine in which year the approximate life expectancy will be 80.9 years.

y=0.189x+70.8
80.9 = 0.189x+70.8
0.189x = 10.1
x = 53.4
Then year is: 1970 + 53.4 = 2023.4
Answer Year 2023
