Answer:
progressive.
Explanation:
Data provided in the question
Family earns = $20,000
Income tax paid = $1,500
In the other case,
Family earns = $40,000
Income tax paid = $3,200
The tax rate in the first case is
= Income tax paid ÷ family earning
= $1,500 ÷ $20,000
= 7.5%
The tax rate in the second case is
= Income tax paid ÷ family earning
= $3,200 ÷ $40,000
= 8%
As we can see that with the increase in income the income tax rate is also increases that reflect the progressive taxation
