Assume that Bestbuy wants to borrow $$8$ billion and to repay it in ten years. It intends to borrow, on Jan $1,2023,$ by issuing one of the following bonds:

i$)$  Ten year maturity, $7\%$ annual coupon, paid semi$-$annually on June $30$th and Dec $31$st$.$

ii$)$  Ten year maturity zero coupon bonds

iii$)$  Ten year maturity, $12\%$ annual coupon, paid semi$-$annually as above

A$)$  For each of the three choices, how many bonds will it have to issue to raise the $$8$ billion it needs? Assume that each bond has a face value of $$1,000,$ and that the cost of debt for Best buy is $7\%$ per year, APR.

B$)$  For each year from $2023$ to $2032,$ list the total dollar amount, in millions, it will have to pay to the bondholders. Just the total $$$$,$ not the discontinued present value.
