Final answer:
The discount on the Tano Company bonds at issuance is $4,247, calculated as the difference between the par value of $81,000 and the selling price of $76,753.
Step-by-step explanation:
The discount on bonds is the difference between the par value and the price at which the bonds are sold. In this case, Tano Company issued bonds with a par value of $81,000, but they sold the bonds for $76,753. Therefore, the amount of the discount on these bonds at issuance is the difference between these two amounts.
To calculate the discount, you subtract the selling price from the par value: $81,000 - $76,753 = $4,247. So, the bonds were issued at a discount of $4,247.
