Answer:
The amount of income tax she pays is $3680.
Step-by-step explanation:
This question can be solved using a rule of three.
Her taxable income, which is $18400, is 100% = 1. She pays x, which is 20% = 0.2. Then
$18400 - 1
$x - 0.2
x = 18400*0.2
x = 3680
The amount of income tax she pays is $3680.
