muminat
The complete sentence should be:

<span><em>Composite</em> numbers can be written as a product of <em>prime</em> factors. This is called the prime factorization of a number.

A prime number is a number that can't be divided by any other number other than 1 or itself. Otherwise, that is a composite number. For example, 50 is a composite number. Through prime factorization,

                  50
                 /   \
               10  5
               /  \
             5  2

The prime factors of composite number 50 are 5, 5 and 2.</span>

Lapatulllka [165]

He pays in interest of $111.0375. Interest is calculated in the two ways, by compounding or by simple interest.

<h3>How to calculate simple interest amount?</h3>

If the initial amount (also called as principal amount) is P, and the interest rate is R % annually, and it is left for T years for that simple interest, then the interest amount earned is given by:

I = \dfrac{P \times R \times T}{100}

The given data in the problem is;

The principal is,P=$2700

The rate of interest = 3.5%

The total time interval is,T

The total time interval is;

\rm T= 5+365+31+21\ days

The simple interest is found as;

\rm SI = P \times R \times T \\\\ \rm SI = 2700 \times 0.0035 \times 1.172222 \\\\ SI=111.0375

Hence, he pays in interest of $111.0375.
