 ```Hi denise! The basic formula for answering all the questions you ask is the bond valuation formula. That is, that the price of a bond should be the present value (discounted at the yield to maturity rate) of its coupon and face value payments. The formula is: P = C1/(1+i) + C2/(1+i)^2 + C3/(1+i)^3 + ... + (F+Cn)/(1+i)^n where P is the price of the bond C1, C2, ..., Cn are the coupon payments i is the yield to maturity F is the face value of the bond n is the number of periods to maturity Question 1 A. I assume for this question that the face value of the bond is \$1,000. The current yield is simply the coupon payment divided by the price of the bond. Since the coupon rate is 8%, the payment is 8% of \$1,000, which is \$80. Now, since the price of the bond is \$1,100, Current Yield = 80/1100 = 0.072 = 7.2% B. Using the notation I described above, we have for this problem that: P = 1100 C1 = C2 = ... = Cn = 80 i = unknown F = 1000 n = 10 Thus, with the bond price formula, we have one equation with one unknown, thus we can find the value of i. In order to do it, use a financial calculator. Here's an online yield to maturity calculator: Yield to Maturity Calculator http://www.investopedia.com/calculator/AOYTM.aspx Entering the values for this problem, we get that the YTM is 6.6% Question 2 I assume again that this bond has a face value of \$1,000. A. Since the coupon rate is 8%, bondholders get \$80 per year B. Again we must solve the previous equation with one unknown, although the unknown this time is P rather than i (which in this case we know to be 7%). Again, you can use a financial calculator to get this. Here's an online bond price calculator: Bond Price Calculator http://www.investopedia.com/calculator/BondPrice.aspx Filling in the known values (use 1000 for "redemption value", which is the same as face value), we get that the price of this bond is \$1,065.15 C. Using 6% yield instead of 7% gives that the bond price rises to \$1,136.03. Google search terms "bond price" calculator "yield to maturity" calculator I hope this helps! Best wishes, elmarto```
