Setler [38]

Answer:

~ <em>50 centimeters of the poster ~</em>

Step-by-step explanation:

Let us plan out our steps, and solve for each:

<em>1. Given the information, let us create a proportionality as such:</em>

<em />

     5         =           1      ⇒   x - centimeters of the poster

     x                     10

<em>2. Now let us cross multiply, and solve through simple algebra for x:</em>

5 * 10 = x,

x =<em> 50 centimeters of the poster </em>

A newspaper advertisement offers a $6500 used car for nothing down and 36 easy monthly payments of
NNADVOKAT [17]

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

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:

I = 584.8, P = 6500, t = 3, hence:

I = Prt

584.8 = 6500(3)r

r = \frac{584.8}{6500 \times 3}

r = 0.03

The simple interest rate was of 3%.
