Answer:
Step-by-step explanation:
Taxable income - 150,000
Federal tax = [28,457.50 +28%*(150,000-146,500)] = 29465.5
Average tax rate = Total tax/Taxable income=29465.5/150,000=19.64%
Effective tax rate = Total tax/Total income
Total income= Taxable income+Income from investment=150,000+40,000=190,000
So, Effective tax rate = 29465.5/190,000=15.51%
