Answer:
16.0%
16.0%
Step-by-step explanation:
Given that :
First $20,000 is exempt from tax
$20000 to $50000 = 12% tax rate
Over $50000 = 16% tax rate
Earning = $90000
Since earning is greater than $50000
Tax rate = 16% = 0.16
Average tax rate = tax paid / taxable income
Tax paid = 0.16 * 90,000 = $14,400
Average tax rate = 14,400 / 90,000
Average tax rate = 0.16 = 16%
Marginal tax rate :
Change in tax paid / change in earning
Suppose ; amount earned increases to 95,000
Tax paid = 95000 * 0.16 = 15200
Change in tax paid = (15200 - 14400) = 800
Change in earning = 95000 - 90000 = 5000
= 800 / 5000
= 0.16 = 16%
Marginal tax rate = 16%
