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:

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:
, hence:




The simple interest rate was of 3%.

(Area of 1) + (Area of 2) = (Area of 3) this statement about the squares must be true.
What is Right angle traingle?
A right-angled triangle is a particular kind of triangle in which one of the angles is 90 degrees. The combined angles of the other two are 90 degrees. The triangle's base and perpendicular sides both include the right angle. The longest of the three sides, known as the hypotenuse, is the third side.
we know that;
By applying the Pythagorean Theorem;
 .............................(1)
                                                                 .............................(1)
Area of the square says A1;
A1 = a^2 unit^2                                                           ...............................(2)
Area of the square says A2;
A2 = b^2 unit^2                                                         .................................(3)
Area of the square says A1;
A3 = c^2 unit^2                                                         ..................................(4)
Replace the A1, A2, and A3 values in the equation 1 ;
A3 = A1 + A2
 therefore;
(Area of 1) + (Area of 2) = (Area of 3).

Answer:
I think 478.4   ._.
Step-by-step explanation:
First, find out how many gallons of gasoline she can buy with $18.50 by dividing 18.50 by 1.25 to get 14.8 gallons. Then, since he already has 6 gallons in his tank, add 6 to 14.8 = 20.8. Finally multiply this by the ratio of gallons to miles (23) to get 478.4
