a bacteria pop. grows exponentially. There are 1500 bacteria after 3 hours and 20,000 after 8 hours.
ahving trouble finding the initial bacteria pop.
thanks for the help
In five hours the population get's larger by a factor 13 + 1/3>
N(t) = N_0 * (13 + 1/3)^(t/5 hours)
Insert in here t = 3 hours and solve for N _0:
N_0 = N(3 hours)* (13 + 1/3)^(3/5) = 317
thanks
