Answer
Explanation:
Step1: Calculate tax for the first - part
The first $7000$ of taxable income is taxed at 10%. So the tax for this part is $7000\times0.1 = 700$.
Step2: Calculate the amount in the second - part
The amount of income in the range from $7000$ to $28400$ is $28400 - 7000=21400$. The tax rate for this part is 15%. So the tax for this part is $21400\times0.15 = 3210$.
Step3: Calculate the amount in the third - part
The remaining income is $45000 - 28400 = 16600$. The tax rate for this part is 25%. So the tax for this part is $16600\times0.25=4150$.
Step4: Calculate the total tax
The total tax is $700 + 3210+4150=8060$.
Step5: Calculate the average tax rate
The average tax rate is $\frac{8060}{45000}\approx0.1791$.
Answer:
$0.1791$
