A stem and leaf plot is a table where each of the data is divided into two parts. The stem, that is the first digit and the leaf is the last digits. Let's say that we have the following set of data.

If we want to make a stem and leaf plot of that data, we first write a column where we place the first digit of each number without repetition, like this:

These are the stems. Now the leaves are the last digit of each number put in order next to the corresponding first digit, like this:
Answer:

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

where
y ----> represent the pool’s loss of water
x ----> the number of days
a is the initial value
a=25,700 gal
b ----> is the base
r=15%=15/100=0.15
b=(1-r)=1-0.15=0.85
The function is equal to

Answer: Richter Scale
