Hi, I am on my last five problems for my textbook prep assignment this week and I was a little confused on how to do these? I am hoping you can help me by also explaining how to get to the solution. Thank you so much.

1.A City of Los Angeles muni bond has a yield of 3.4%. What is the tax equivalent yield for an investor in the 25% tax bracket compared to an investor in the 35% tax bracket?

2.What would you be willing to pay for a $1000 par, 6% coupon bond with 15 years until maturity if you wanted to earn a return of 7%? What if you only needed to earn a return of 5%? What if you wanted to earn 6%?

3.If you purchase a $1000 par value bond for $1025 that has a 7 5/8% coupon rate and 15 years until maturity, what will your annual return be?

4.Builtrite bonds have the following: 7 % coupon, 14 years until maturity and are currently selling at $984.

a.If you purchase the above bond, what would be your AYTM?

b.If you want to make an 8% return, what would you be willing to pay?

5.Builtrite sold 15 year, zero coupon bonds yielding 5%. What did they sell for?
