I don't know if this is what you are looking for, but here is it simplified: 21-2x
Assuming that I am properly understand your question, all you have to do is get the initial values for each individual and add their savings monthly.
Starting
Josie: 80
Addie: 60
One month
Josie: 110
Addie: 100
Two months
Josie: 140
Addie: 140
So two months would be the answer.
You could also do...
x = months
80 + 30x = 60 + 40x
20 + 30x = 40x
20 = 10x (Divide by ten on both sides)
2 = x
2 Months
The term that is not possible in the domain of a sequence is:
-5.
<h3>What is the domain of a function?</h3>
The domain of a function is the set that contains all possible input values for the function. For a sequence, the domain is the set that contains all the indexes of the terms, starting at 0 and going until the nth term.
For example, suppose we have the following sequence: 3, 5, 7, ...
- The term with index 0 is 3.
- The term with index 1 is 5.
- The term with index 2 is 7.
From what was explained above, which also can be visualized with the example, an index term of a sequence cannot be negative, hence the term that is not possible in the domain of a sequence is:
-5.
Which is the only negative number of the options.

Step-by-step explanation:
Amount of green clay at the start = 57g + 31g = 88g.
