Answer:

Step-by-step explanation:
In this problem we have a exponential function of the form

where
x is the time in hours
y is the numbers of bacteria
a is the initial value
b is the base
r is the rate of growth
b=(1+r)
we have that

For x=8, y=3,300
substitute in the exponential function

solve for b

![b=\sqrt[8]{1.1}](https://tex.z-dn.net/?f=b%3D%5Csqrt%5B8%5D%7B1.1%7D)

Find the value of r

The equation is equal to

For x=12 hours
substitute the value of x in the equation

Total Attendence = Mean Attendence × No. of Incidents
= 24,500 × 25
= 612,500.
Answer and Explanation:
Gina wanted to swim at the pool. She is allowed to spend at most $30. The cost to swim in the pool is 3 dollars per hour plus a flat fee of $3. How many hours can Gina swim without going over her spending limit?
This problem can be represented by
.
'x' would be the number of hours. "At most" means less than or equal to. So, the value of x would have to be less than or equal to 30.

So, Gina would have a maximum of 9 hours to swim in the pool.
Hope this helps.
