is the initial population at ... which is 500.
you were given another point on the curve ,
so, sub in 200 for B and 2 for t ... solve for k.
I have no idea where to start. Any ideas?A lab culture initially contains 500 bacteria. Two hours later, the number of bacteria has decreased to 200. Find the exponential decay model of the form
that can be used to approximate the number of bacteria after hours.
