Chuck, a single taxpayer, earns $75,000 in taxable income and $10,000 in interest from an investment in City of Heflin bonds.

Using the U.S. tax rate schedule, how much federal tax will he owe? What is his average tax rate? What is his effective tax rate? What is his current marginal tax rate? (Round your answers to 2 decimal places. Do not round intermediate calculations. Omit the "$" and "%" signs in your responses.)
