Roger purchased a $10,000 face value Ontario Hydro Energy bond maturing in six years. The coupon rate was 8.5% payable semiannually. If the prevailing market rate at the time of purchase was 7.8% compounded semiannually, what price did Denis pay for the bond? (Do not round the intermediate calculations. Round your final answer to 2 decimal places.) Assume that:

• Bond interest is paid semiannually.
• The bond was originally issued at its face value.
• Bonds are redeemed at their face value at maturity.
• Market rates of return are compounded semiannually.
