Answer:
24%
Step-by-step explanation:
The computation of the average tax rate is shown below:
Given that
From income $0 to $100, no income tax is applicable
From income above $100 upto $400, the tax rate is 20%
The income above $400, the tax rate is 40%
So based on the above information
Since the Jane doe income is $500
So here the average tax rate is
= (400 × 0.20) + (100 × 0.40) ÷ $500
= ($80 + $40) ÷ ($500)
= ($120) ÷ ($500)
= 24%
