Answer:
Option C, Its marginal tax rate is 18.33%. is correct
Explanation:
The tax payable on its first $50,000 of income is shown below:
tax payable=$50,000*15%=$7500
The tax payable on the remaining balance of $25,000 is computed thus:
tax payable on the balance of $25,000=$25,000*25%=$6250
Total tax payable=$7,500+$6,250=$ 13,750.00
Marginal tax rate=tax payable/taxable income=$ 13,750.00/$75,000=18.33%
