Simple Interest

Simple interest is used when there is a single compounding per time period.

The amount of interest after t years in is modeled by:

[tex]I = Prt[/tex]

In which:

  • P is the initial amount.
  • 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:

[tex]I = 584.8, P = 6500, t = 3[/tex], hence:

[tex]I = Prt[/tex]

[tex]584.8 = 6500(3)r[/tex]

[tex]r = \frac{584.8}{6500 \times 3}[/tex]

[tex]r = 0.03[/tex]

The simple interest rate was of 3%.
