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%.

Answer:
It is possible to find f(x+4) by replacing each occurrence of x by (x+4).
![f(x+4) = x^2 +2x -3](https://tex.z-dn.net/?f=f%28x%2B4%29%20%3D%20x%5E2%20%2B2x%20-3)
Step-by-step explanation:
We are given the following function in the question:
![f(x) = x^2-6x+5](https://tex.z-dn.net/?f=f%28x%29%20%3D%20x%5E2-6x%2B5)
We have to find the value of f(x+4).
It is possible to find f(x+4) by replacing each occurrence of x by (x+4).
This can be done in the following manner:
![f(x) = x^2-6x+5\\f(x+4) =(x+4)^2 - 6(x+4) + 5\\f(x+4) = x^2 + 16 + 8x - 6x - 24 +5\\f(x+4) = x^2 +2x -3](https://tex.z-dn.net/?f=f%28x%29%20%3D%20x%5E2-6x%2B5%5C%5Cf%28x%2B4%29%20%3D%28x%2B4%29%5E2%20-%206%28x%2B4%29%20%2B%205%5C%5Cf%28x%2B4%29%20%3D%20x%5E2%20%2B%2016%20%2B%208x%20-%206x%20-%2024%20%2B5%5C%5Cf%28x%2B4%29%20%3D%20x%5E2%20%2B2x%20-3)
