(a)

Answer to Problem 24SGR
An equation that models the number of bacteria is
Explanation of Solution
Given:
The initial bacteria population is
Calculation:
At the beginning of the experiment, the time is 0 hours and there are
Substitute these values into an exponent function to determine the value of
Simplify further.
Therefore, an equation that models the number of bacteria is
(b)
To find: The number of bacteria that can be expected in the sample after 32 hours.
