Final answer:
Bond A has a coupon rate of 6%, while Bond B has a coupon rate of 8%, calculated by dividing the annual payments by the bond's face value and multiplying by 100%.
Step-by-step explanation:
The coupon rate or interest rate of a bond can be calculated by taking the annual coupon payment and dividing it by the face value of the bond.
For Bond A, which pays $60 annually on a $1000 face value, the coupon rate is 6%, calculated by ($60 / $1000) × 100%.
Similarly, for Bond B, which pays $80 annually on a $1000 face value, the coupon rate is 8%, calculated by ($80 / $1000) × 100%. These rates represent the fixed annual payment to the investor relative to the face value of the bond.
