Assuming annual interest payments and a principal value of $100,
what is the value of a 4-year 6.8% coupon bond when the discount
rate is i) 4.8%, ii) 6.8%, and iii) 7.1%? Show that your results
are consistent with the relationship between the coupon rate,
discount rate, and price relative to par value.
-->(I looked the sample but didn't get it very well), Please
explain it clearly, Thank you
