1. The problem statement, all variables and given/known data
The practical limit to ages that can be determined by radiocarbon dating is about 41000 yr. in a 41000 yr old sample, what percentage of the original carbon-14 remains?

2. Relevant equations

3. The attempt at a solution
I don't know where to start....

Look at the variables in that equation. Which of them do you know, or can find out? And which represent the thing you're trying to find?

Nope

I think t=41000, N/No is what i need?
But how do you determine the half life?

Look it up. I think you should find something like 5700 years.

$$N_0$$ is the initial percentage of carbon-14, so it would be 100. So we need to find what percentage remains.
