Final answer:
The amount of premium amortized in the 6th coupon payment of the bond is $2.50.
Step-by-step explanation:
The amount of premium amortized in the 6th coupon payment of the bond can be calculated by subtracting the coupon rate from the yield on the bond.
First, let's calculate the coupon payment for each semiannual period. Since the par value of the bond is $1000 and the coupon rate is 8%, the coupon payment for each period will be $1000 x 8%/2 = $40.
The yield on the bond is given as 7.5% convertible semiannually. To convert this to a semiannual yield, we divide it by 2, resulting in a semiannual yield of 7.5%/2 = 3.75%.
Now, to calculate the premium amortized in the 6th coupon payment, we need to find the difference between the coupon payment and the semiannual yield. In this case, it would be $40 - 3.75% of the par value ($1000) = $40 - $37.50 = $2.50.
Thus, the amount of premium amortized in the 6th coupon payment is $2.50.
