This is important i need to turn this in tomorrow, how many half-lives does it take to get from 1,000 to 125, and in what region of virginia would you find young and old rivers. you in advance!

It takes 3 half-lives:
1. 1000 -> 500
2. 500 -> 250
3. 250 ->125

I'm not sure about the Virginia thing so good luck!

And congratulations on being my first answer-person!!
