Solution

a) Tax payable on $75,000 = 5226.25+25%*(75000-37950)= $      14,488.75 Tax payable on $115,000 = 18713.75+28%*(115000-91900) = $      25,181.75 Marginal tax rate on the additional income = (25181.75-14488.75)/(115000-75000)= 26.73% Answer b) Tax payable on $35000 = 932.50+15%*(35000-9325) = $        4,783.75 Margina tax rate on the additional deductions = (14488.75-4783.75)/(75000-35000) = 24.26% Answer
