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.
