We will call the first number n, and the second number x.
3n-x=118
2n+x=147
Now, solve one of the equations for x.
x=147-2n
Then, substitute this into the other formula for x.
3n-(147-2n)=118
Next, solve for n:
3n-147+2n=118
5n=265
n=53
^^^That's your first number.
Lastly, plug in 53 for n into either equation to solve for x.
2(53)+x=147
106+x=147
x=41
^^^This is your second number.
Answer:
3
Step-by-step explanation:
Because f(x) = 3, any value of x will make f(x) = 3. So when x = 0, f(x) = 3.

The table can be filled in as follows:

After 3 days, Kim's savings already exceeds Ben's, and is increasing at a faster rate. The appropriate descriptor is ...
... Kim will save more than Ben
_____
An exponential function increases faster than any polynomial function. (A linear function is a polynomial function.)
If Kim keeps up her savings for 28 days, her account balance will exceed the US Gross National Product of more than $20 trilliion. (Exponential functions tend to increase very rapidly!) Meanwhile, Ben's savings will be $89 on day 28.
_____
Please note the discrepancy in the problem statement. The verbiage says "days", but the table shows "years".
