please answer both questions (last question I have on my account)

Single Company buys inventory from Double Company on October 1 and gives a 2 month, 12% Note for $6,000. Single defaults on its payment on the maturity date of the Note. The entry that Single should make at this time includes Multiple Choice O None of these 0 A credit to interest income of $480 A debit to interest expense of $80 O A credit to interest income of $80 O O A debit to interest expense of $480 A company may either borrows $1,000,000 by issuing, at par, twenty-year, 10 percent bonds with semiannual coupons or obtain the $1,000,000 by undertaking a twenty-year mortgage with an implicit borrowing rate of 10 percent, the annual payments are $1,000,000/8.51356 = $117,460. If the bonds are held to maturity and the mortgage is not prepaid, i.e., both borrowings run their respective 20 year term, the total interest expense will be Multiple Choice O More under the mortgage financing 0 The same under both financing strategies 0 The difference is not material (less than $10) More under the bond financing O None of the other alternatives are correct
