Answer:
$4,225.6
Step-by-step explanation:
Jenifer had the following deductions from her monthly pay
Federal income tax of $87
State income tax of 2.5% of gross pay
City income tax of 1.2% of gross pay
Jennifer monthly pay is $3,982.22
Therefore jenifer monthly gross pay can be calculated as follows
Let x represent the gross pay
x = 3982.22 + 87 + 1.2/100x + 2.5/100x
x = 3982.22 + 87 + 0.012x + 0.025x
x =4069.22 + 0.037x
Collect the like terms
x - 0.037x = 4069.22
0.963x = 4069.22
Divide both sides by the coefficient of x
x = 4069.22/0.963
x = 4,225.6
Hence Jennifer monthly gross pay is $4,225.6
