Julli [10]

The annual salary of Mrs. Fredrick is $ 39397.2

Solution:

Given, Mrs. Frederick is paid semimonthly.

Her semi-monthly salary is $1.641.55.

Now, let us find her monthly salary first.

monthly salary = 2 x semi – monthly salary

So, monthly salary = 2 x 1,641.55 = $ 3283.1

Since there 12 months in a year, we obtain the annual salary as follows:

Now, the annual salary = 12 x monthly salary

Annual salary = 12 x 3283.1 = $ 39397.2

Hence, the annual salary of Mrs. Fredrick is $ 39397.2

his income must be "x" which is the 100%, and we would know that 0.2% of that is 12.37.

$\begin{array}{ccll} amount&\%\\ \cline{1-2} x&100\\ 12.37&0.2 \end{array}\implies \cfrac{x}{12.37}=\cfrac{100}{0.2}\implies 0.2x=1237 \\\\\\ x=\cfrac{1237}{0.2}\implies x=61.85$

his income must be "x" which is the 100%, and we would know that 2% of that is 12.37.

$\begin{array}{ccll} amount&\%\\ \cline{1-2} x&100\\ 12.37&2 \end{array}\implies \cfrac{x}{12.37}=\cfrac{100}{2}\implies 2x=1237 \\\\\\ x=\cfrac{1237}{2}\implies x=618.5$
