I have attached a Word document with the problem I need help with. I would appreciate any help. Thanks.

a. What is the selling price of bonds with a face value of $8,000,000, a stated rate of 5% payable semiannually, and a 10-year term, when the market rate of interest for similar bonds is 6%? Problem b. Kansas Kites is preparing a contract to lease a machine to Jabo Company for a period of 10 years. Kansas Kites purchased the machine for $1,500,000 and would like to earn a return of 5% on its investment. If the contract is to provide for 20 semiannual payments beginning on the date the lease is signed, what should be the amount of each semiannual lease payment? c. Overland Corporation recently issued $20 million in 10-year bonds. Overland wishes to make annual contributions to a sinking fund to accumulate sufficient funds to retire the bonds at the end of their term. If Overland makes annual deposits in the sinking fund of $1,500,000 at the end of each year, what must be the annual yield (interest rate) on the deposits to accumulate the needed funds
