<span>A parallelogram can be divided into two congruent triapezoids. The area of each trapezoid is one-half the area of the parallelogram. The two parallel sides of atrapezoid are its bases. If we call the longer side b1 and the shorter side b2, then the base of the parallelogram is b1+b2</span>

The amount that Susan will have to pay in interest is given by: Option A: $5.33 approx.

<h3>How to find the percentage from the total value?</h3>

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

$\dfrac{a}{100} \times b$

For this case, we're given that:

Amonut Susan took out = $200
Interest rate = 32% annually (interest rates are usually expressed in annual (yearly) terms).
Amount paid off within 1 month

The interest was 32% annually, so in monthly terms, it would be 32/12 = 2.667% approx. (as there are 12 months in each year)

Since the balance was paid within one month, the interest would be simply 1 time calculated on the main balance.

Thus, we get:
Interest amount ≈ 2.667% of $200 = $\dfrac{200}{100} \times 2.667 = 5.334 \approx 5.33 \: \rm (in \: dollars)$
