Can you please help me with the calculation to work on finding the answer to the following problem:

A company's 5-year bonds are yielding 8.1% per year. Treasury bonds with the same maturity are yielding 6.95% per year, and the real risk-free rate (r*) is 2.8%. The average inflation premium is 3.75%, and the maturity risk premium is estimated to be 0.1 x (t - 1)%, where t = number of years to maturity. If the liquidity premium is 0.8%, what is the default risk premium on the corporate bonds? Round your answer to two decimal places
