    \[P = 258e^{kt}\] And we know that when t = 10 (in 2000), P = 478000 . Use logs and you should be able to do it.

    Well i solved it but the answer I got which was .7524 is being marked incorrect. I may be doing something wrong.

    Oh, sorry, you need to use 478000 as 478 (and the formula gives it in thousands) - or use 258000
