Question 452699: Suppose that the number of bacteria in a certain population increases according to an exponential growth model, with a growth rate of 13% per hour. Suppose also that a sample culture of 2800 bacteria is obtained from this population. Find the size of the sample after three hours. Round your answer to the nearest integer.

Suppose that the number of bacteria in a certain population increases according to an exponential growth model, with a growth rate of 13% per hour. Suppose also that a sample culture of 2800 bacteria is obtained from this population. Find the size of the sample after three hours. Round your answer to the nearest integer.
---------------------
A(t) = 2800*(1.13)^t
----
A(3) = 2800*(1.13)^3
---
A(3) = 4040
