Iron-59 has a half-life of 45.1 days. How old is an iron nail if the Fe-59 content is 25% that of a new sample of iron? Show all calculations leading to a solution. I am really confused on how to find t here? Can someone help? I can set up the rest of the equation

Didn't I do this a couple days ago for you. Instead of reposting, tell me what you didn't understand about the answer and we can get through it. t is the only unknown in the equation.

I have never had this done for me? I am still confused on how to find t?
