1. Skysong Inc. has completed the purchase of new Dell computers. The fair value of the equipment is $ 906,565. The purchase agreement specifies an immediate down payment of $ 220,000 and semiannual payments of $ 84,647 beginning at the end of 6 months for 5 years. What is the interest rate, to the nearest percent, used in discounting this purchase transaction?

2.Skysong Inc. loans money to John Kruk Corporation in the amount of $ 880,000. Skysong accepts an 8% note due in 7 years with interest payable semiannually. After 2 years (and receipt of interest for 2 years), Skysong needs money and therefore sells the note to Chicago National Bank, which demands interest on the note of 10% compounded semiannually. What is the amount Skysong will receive on the sale of the note?

3. Skysong Inc. wishes to accumulate $ 1,430,000 by December 31, 2030, to retire bonds outstanding. The company deposits $ 220,000 on December 31, 2020, which will earn interest at 10% compounded quarterly, to help in the retirement of this debt. In addition, the company wants to know how much should be deposited at the end of each quarter for 10 years to ensure that $ 1,430,000 is available at the end of 2030. (The quarterly deposits will also earn at a rate of 10%, compounded quarterly.)
