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
