Exponential growth rate?

Help please
Suppose that the number of bacteria in a certain population increases according to an exponential growth model. A sample of 1800 bacteria selected from this population reached the size of 2029 bacteria in three hours. Find the continuous growth rate per hour.


Write your answer as a percentage. Do not round any intermediate computations, and round your percentage to the nearest hundredth.

Hi Campus,



a = the initial amount before measuring growth.
r = the growth rate per time period written as a decimal.
x = the number of time intervals
y = ending amount after growth period
