Answer:
The monthly net pay is $1555 .
Step-by-step explanation:
As given
Quintina decided to increase the deduction percentage of her federal income tax rate from 14% to 16%.
Quintina’s gross pay per month is $2,100.
16% is written in the decimal form .
![= \frac{16}{100}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B16%7D%7B100%7D)
= 0.16
Federal income tax = 0.16 × Gross pay
= 0.16 × 2100
= 336
Monthly net pay = Gross pay - Federal income tax - State Income Tax - Social Security - Medicare
= 2100 - 336 - 89 - 85 - 35
= 2100 - 545
= $1555
Therefore the monthly net pay is $1555 .
