Step-by-step explanation:
The carrying value of a bond issued at a discount is calculated by subtracting the balance of the discount account from the balance of the Bonds Payable account.
For example, if a bond is issued at a discount of $500 and the Bonds Payable account has a balance of $10,000, the carrying value of the bond would be $10,000 - $500 = $9,500.
