Violet contributes 12% of her $55,700 annual salary to her 401(k) plan. What is her pretax income?

NikAS [45]

You have that:

- Her contribution from her salary to her 401(k) plan, is: 12%.
- Her annual salary is: $55,700.

Then, to solve this problem and calculate her pretax income, you must following the steps below:

1. You must calculate the amount that Violet contributed to her 401(k) plan. So, you have:

12%/100=0.12

($55,700x0.12)=$6,684

2. Now, you must subtract her annual pay ($55,700) by the amount obtained ($6,684), as below:

Pretax income= $55,700-$6,684
 Pretax income=$49,016

What is her pretax income?

The answer is: Her pretax income is $49,016

Find ten rational numbers between -1 by 5 and 1 by 2

uysha [10]

Answer:

Step-by-step explanation:

First both the rational numbers should have same denominators. So, find least common denominator

Least common denominator is 10

$\frac{-1}{5}=\frac{-1*2}{5*2}=\frac{-2}{10}\\\\\\\frac{1}{2}=\frac{1*5}{2*5}=\frac{5}{10}\\\\\\$

Now multiply the numerator and denominators of the both the numbers by 10.

$\frac{-2*10}{10*10}= \frac{-20}{100} \ and \ \frac{5*10}{10*10}=\frac{50}{100}\\\\\\Now\ 10 \ rational \ numbers \ between\frac{-20}{10} \ and \ \frac{50}{100} \ is \\\\\\\frac{-19}{100},\frac{-18}{100},\frac{-17}{100},\frac{-16}{100}.\frac{-15}{100},\frac{-14}{100},\frac{-13}{100},\frac{-12}{100},\frac{-11}{100};\frac{-10}{100}$
