4. Lets Study Inc. is a tutoring company that is considering issuing bonds to finance the expansion of its activities. The managers thought about bonds with 10 or 15 years to maturity, with a coupon rate of 6%, paid semiannually. The face value of those bonds would be $1,000 and they would expect those bonds to pay just as much as investors require, being sold at par at the issuance date. Suppose that an investor is interested in the companys bonds, and they expect that the interest rates (YTM) are going to change immediately, decreasing by 2 percentage points compared to the YTM at issue. Which maturity bond would be better for this investor, the 10 or 15-year? What would be the dollar gain per bond with the expected immediate YTM change in each case?

5. Find the coupon dollar value and coupon rate of a bond that has face value of $1,000, YTM of 6.55%, semiannual coupon payments, and is quoted at 96.49 of par value.

For number 5 there is no correct answer, please explain why there isn't a number. Thank you.
