Please tell me how to do problem 7, and please give me the correct answer, thank you so much.

7, (5 points) Suppose the interest rate on a 1-year T-bond is 5.00% and that on a 2-year T- bond is 4.10%. Assume that the pure expectations theory is NOT valid, and the MRP is zero for a 1-year T-bond but 0.40% for a 2-year bond, what is the yield on a 1-year T-bond expected to be one year from now? Round the intermediate calculations to 4 decimal places. (Show your work)
