Answer:
3137
Step-by-step explanation:
The decay factor is 400/110,000 = 1/275 in 30 hours. Assuming an exponential decay, the equation for the number remaining can be ...
n(t) = 110,000·(1/275)^(t/30)
Then after 19 hours, the number remaining is ...
n(19) = 110,000·(1/275)^(19/30) ≈ 3137
There will be about 3137 bacteria after 19 hours.
