Question

Samantha Hewitt is a nutritionist. Her weekly salary is `$420.` Of that amount, `6.2%` goes to Social Security taxes and `1.45%` to Medicare taxes. She pays `$10.23` for health coverage and donates `$5.00` to charity. What is her nett pay amount?

Answer 1

Samantha Hewitt's nett pay amount is `$372.64`

Explanation:

To get my answer I did:

`6.2/100 = x/420` for the Social Security taxes

and `1.45/100 = x/420` for Medicare taxes.

I did cross multiplying for both of them to get `100x = 420(6.2)`

and `100x = 420(1.45)`.

In the equation `100x = 420(6.2)," "` I multiplied `420(6.2)`
to get `2,604.`

The equation is now `100x = 2604`

You divide by `100` on both sides to get `x = 26.04.`

She paid `$26.04` for Social Security taxes.

In the equation of `100x = 420(1.45)`, you simplify, so
`420 xx 1.45 = 609.`

The equation is now `100x = 609.`

You divide both sides by `100` to get `x = 6.09.`

She paid `$6.09` for Medicare taxes.

I added all of the expenses:
Social Security taxes: `$26.04`,
Medicare taxes: `$6.09`,
health coverage: `$10.23`,
charity: `$5.00`

to get the total of `$47.36.`

I subtracted this from her weekly salary :

`$420 -`47.36 = $372.64. #

So Samantha's net pay amount is `$372.64.`
