I don't intend to work this problem for you under any name. You take those numbers I gave you earlier and substitute them. Telling me you don't know how to solve for t doesn't help. Substitute the numbers, show me your work, go as far as you can, then tell me what you don't understand about the next step. That's the only way I will know what you don't understand.
It's half life - try looking in your book.
