So a computer virus has been created via Corporate e-mail. Let t=0 be the time of the first 100 infections, and at t=17 minutes the population of infected computers grows to 200. Assume the anti-virus companies arent able to identify the virus or slow its progress for 24 hours, allowing the virus to grow exponentially.

1. What will the population of the infected computer be after 1 hour?

(So i have to set up the equation for P(t)=P_0e^kt, where t=0 for the first 100 infections and t=17 when it grows to 200...but i don't know where to start or set it up) Help please.
