$955.37 per bond
Explanation:
Callable bonds are generally worth less than normal bonds since the call option decreases the value of the bondholder while increases the value of the issuer. Bonds will only be called if the interest rate falls below a certain level and calling them is cheaper (form the issuer's point of view) than keep paying high interest rates.
market price of callable bonds:
current market price of callable bonds = $613.91 + $617.74 - $276.28 = $955.37
