We can use the formula for the present value of a bond to calculate its price:
Bond price = (Coupon payment / Discount rate) x [1 - 1 / (1 + Discount rate)^(Number of coupon payments)] + Par value / (1 + Discount rate)^(Number of coupon payments)
In this case, the coupon payment is $1,000 x 7.40% / 2 = $37, the discount rate is 6.40% / 2 = 3.20%, the number of coupon payments is 25 x 2 = 50, and the par value is $1,000.
Bond price = ($37 / 3.20%) x [1 - 1 / (1 + 3.20%)^50] + $1,000 / (1 + 3.20%)^50
Bond price = ($1,156.25) x (34.9829) + $268.44
Bond price = $40,464.06
Therefore, the bond's price is approximately $40,464.06.
