Question 122136: The United States population (P) (in millions) can be modeled by the function P=2.683t + 213.1 where t is the number of years since 1975. In approximately what year will the population be 350 million?

I have already come up with 2026 by graphing it on my calculator, I just need to know whether or not it is right.

P=2.683t + 213.1 where t is the number of years since 1975. In approximately what year will the population be 350
-----------------
Let P=350 million; solve for "t".
-----------------
350 = 2.683t+213.1
2.683t = 136.9
t = 51.025
--------------------
1975+51.025 = 2026.025
---------------
In approximately 2026 but actually in 2027.
