Final answer:
The coupon rate on the bonds must be 8%.
Step-by-step explanation:
The coupon rate on the bonds of Nikita Enterprises must be 8%.
The coupon rate is the annual interest payment as a percentage of the bond's par value.
In this case, the bond has a par value of $1,000 and is selling for $972, which means the bond is selling at a discount.
To calculate the coupon rate, we can use the formula: Coupon rate = Annual interest payment / Par value of the bond.
Since the bond is selling for $972, we can determine that the annual interest payment is ($1000 - $972) = $28.
Therefore, the coupon rate is 28/1000 = 0.028 or 2.8%.
