From 1994 to 1998, the number of personal computers connected to the Internet grew according to the formula $N(t) = 2.8e^{0.85t}\text{,}$ where $t = 0$ in 1994 and $N$ is in millions. (Source: Los Angeles Times, September 6, 1999)

1. Evaluate $N(1)=$ . By what percent did the number of Internet users grow in one year?
   About %
2. Express the growth law in the form $N(t) = N_0 (1 + r)^t\text{.}$
   $N(t)=$
