<PRE><B>Question 981314</B>
A colony of bacteria grows at an exponential rate according to the function,
P(t)=800e^{0.03t} , which describes the number of bacteria P at time t (in hours). 

A)   Find the population after 12 hours. (Round your answer to the nearest whole number.) 
--------------
P(t)=800e^{0.03t}
Sub 12 for t.
=========================================
B)   When will the population double? (Round your answer to the nearest whole number.)
P(t)=800e^{0.03t}
===================================
800e^{0.03t} = 2*800e^{0.03t}
Solve for t.
