Using simple interest, it is found that:
- The total amount paid was of $7,084.8.
- The finance charge was of $584.8.
- The simple interest rate was of 3%.
<h3>Simple Interest</h3>
Simple interest is used when there is a single compounding per time period.
The amount of interest after t years in is modeled by:
![I = Prt](https://tex.z-dn.net/?f=I%20%3D%20Prt)
In which:
- r is the interest rate, as a decimal.
In this problem, the amount paid was of 36 monthly payments of
$196.80, hence:
36 x 196.80 = $7084.8.
The total amount paid was of $7,084.8.
The original price is of $6,500, hence the finance charge was of:
7084.8 - 6500 = $584.8.
For interest, we have that:
, hence:
![I = Prt](https://tex.z-dn.net/?f=I%20%3D%20Prt)
![584.8 = 6500(3)r](https://tex.z-dn.net/?f=584.8%20%3D%206500%283%29r)
![r = \frac{584.8}{6500 \times 3}](https://tex.z-dn.net/?f=r%20%3D%20%5Cfrac%7B584.8%7D%7B6500%20%5Ctimes%203%7D)
![r = 0.03](https://tex.z-dn.net/?f=r%20%3D%200.03)
The simple interest rate was of 3%.

6*2 = 12
12/2 = 6
So, the answer could be 12/2
Answer:
![(-\infty,-9)\cup(-9,\infty)](https://tex.z-dn.net/?f=%28-%5Cinfty%2C-9%29%5Ccup%28-9%2C%5Cinfty%29)
Step-by-step explanation:
The domain of a rational function is all real numbers <em>except </em>for when the denominator equals 0.
So, to find the domain restrictions, set the denominator to 0 and solve for x.
We have the rational function:
![s(y)=\frac{7y}{y+9}](https://tex.z-dn.net/?f=s%28y%29%3D%5Cfrac%7B7y%7D%7By%2B9%7D)
Set the denominator to 0:
![y+9=0](https://tex.z-dn.net/?f=y%2B9%3D0)
Subtract 9:
![y\neq-9](https://tex.z-dn.net/?f=y%5Cneq-9)
So, the domain is all real numbers except for -9.
In other words, our domain is all values to the left of negative 9 and to the right of negative 9.
In interval notation, this is:
![(-\infty,-9)\cup(-9,\infty)](https://tex.z-dn.net/?f=%28-%5Cinfty%2C-9%29%5Ccup%28-9%2C%5Cinfty%29)
And we're done :)
