Thank you so much for the help! I would really appreciate it if you could show steps for the first one!

4. What is the yield to call (YTC) of a 20 year 8% bond selling for $1030? The call deferment period for the bond is 5 years.

5. What is the holding period yield on a 30 year 7% bond that we buy for $1050. We sell the bond in 4 years for $1090.

6. Suppose you bought a 20 year 8% bond for $1075. If you sold the bond for $980 after holding it for 2 years, what was your holding period yield?

Thanks again!
