I need help with #4; the PREMIUM instead of discount is throwing me.

Vaughn Co. reported before-tax income of $432,000 in 2017 and $346,000 for 2018. However, the company's new controller found that the following errors had been made: 1. Sales for 2018 included $20,900 which had been received in cash during 2018, but for which the related products were delivered and title passed to the purchaser in 2017. 2. Inventory on December 31, 2017, was overstated by $6,300. 3. Ordinary repairs to equipment in the amount of $18,300 were erroneously charged to the Equipment account during 2017. The company recorded a full year of depreciation on this amount in 2017 and 2018 on a straight-line basis assuming a 10-year life. 4. The bookkeeper in recording interest expense for both 2017 and 2018 on bonds payable made the following entry on an annual basis. Interest Expense 24,750 Cash 24,750 The bonds have a face value of $225,000 and pay a stated interest rate of 11%. They were issued at a premium of $8,529 on January 1, 2017, to yield an effective-interest rate of 10%. (Assume that the effective-yield method should be used.)
