The number of bacteria in a certain population increases according to a continuous exponential growth model at a rate of 8.1% per hour. There are 1800 bacteria at t = 0.
Write an equation that gives the number of bacteria after t hours.

Step-by-step explanation:

Subtract 2 and two-thirds from both sides of the equation

8 minus 2 and two-thirds = 5 and one-third

Substitute the value for r to check the solution.

Step-by-step explanation:

2 2/3  + r   = 8

Subtract 2 2/3 from each side

2 2/3  + r  - 2 2/3   = 8 - 2 2/3

r = 5 1/3

Check the solution

2 2/3 +5 1/3 =8

8 =8
