3.- Bond interest expense on first payment<em> 7076.33</em>
Explanation:
1.-
![Nominal \times \frac{issued \: points}{100}= cash\: proceeds\\250,000 \times \frac{123 + 3/8}{100} = 308,473.5](https://tex.z-dn.net/?f=Nominal%20%5Ctimes%20%5Cfrac%7Bissued%20%5C%3A%20points%7D%7B100%7D%3D%20cash%5C%3A%20proceeds%5C%5C%3C%2Fp%3E%3Cp%3E250%2C000%20%5Ctimes%20%5Cfrac%7B123%20%2B%203%2F8%7D%7B100%7D%20%3D%20308%2C473.5)
Notice that it is (123 + 3/8) is a percent (%) that's why is important to divide by 100
2.-
308,473.5 - 250,000 = 58473.5 premium on bonds
This decrease the interest expense from the cash proceeds
Cash proceeds
250,000 * 0.04 * 20 = 200,000
- Amortization on Premium (58473.5)
Interest Expense <em><u>141526.5</u></em>
3.-
It will use <u>striaght-line method so</u>
![\frac{premiun \: on\: bonds}{total \: payments}= amortization \: per \: payment](https://tex.z-dn.net/?f=%5Cfrac%7Bpremiun%20%5C%3A%20on%5C%3A%20bonds%7D%7Btotal%20%5C%3A%20payments%7D%3D%20amortization%20%5C%3A%20per%20%5C%3A%20payment)
10 years * 2 payment per year = 20 payment in the lifetime of the bond
58473.5/20 = 2923.67
Cash proceeds - Premimun = Interest Expense
10,000 - 2923.67 = 7076.33
