can you answer these questions for me please ?

Required: A bond has a par value of $1,000, a time to maturity of 10 years, and a coupon rate of 8.40% with interest paid annually. If the current market price is $840, what will be the approximate capital gain of this bond over the next year if its yield to maturity remains unchanged? (Do not round intermediate calculations. Round your answer to 2 decimal places.) Suppose you just purchased a bond (Face Value =$1,000 ) with 12 years to maturity that pays an annual coupon of $36.00 and is selling at par. Calculate the one-year holding period return for each of these two cases: Required: a. The yield to maturity is 5.50% one year from now. (Do not round intermediate calculations. Negative value should be indicated a minus sign. Round your answer to 2 decimal places.) b. The yield to maturity is 2.30% one year from now. (Do not round intermediate calculations. Round your answer to 2 decimal places.)
