Could you please give me the answer to these 2 questions:

1. Figure the present value of a previously issued bond.

Purchase of a 10 year bond with 7 years to go to maturity, with a face value of 1,000 that pays an annual coupon of $40 and the interest rate is running at 5.5% how much should you pay for that bond now?

2. Also, if you are thinking about buying a 10 year bond with 5 years to go to maturity, with a face value of 1,000 that pays an annual coupon of $50.00 and interest rate is 4.5%, what should you pay for this bond

We do not help people with homework, we provide direction and help with roadblocks. I have found a great Bond Price Primer (http://www.investopedia.com/university/advancedbond/advancedbond2.asp#axzz1orF9eHOB) from Investopedia.
