I don't understand this. Please thoroughly explain. Im trying to complete with paper and pencil. Please fully explain how I show calculate not understanding how.P$6-31$ Bond valuation and yield to maturity Mark Goldsmith's broker has shown him

two bonds issued by different companies. Each has a maturity of five years, a par value

of $$1,000,$ and a yield to maturity of $7\mathrm{.}5\%.$ The first bond is issued by Crabbe Waste

Disposal Corporation and has a coupon rate of $6\mathrm{.}324\%$ paid annually. The second bond,

issued by Malfoy Enterprises, has a coupon rate of $8\mathrm{.}8\%$ paid annually.

a$.$ Calculate the selling price for each bond.

b$.$ Mark has $$20,000$ to invest. If he wants to invest only in bonds issued by Crabbe

Waste Disposal, how many of those bonds could he buy? What if he wants to

invest only in bonds issued by Malfoy Enterprises? Round your answers to the

nearest integer.

c$.$ What is the total interest income that Mark could earn each year if he invested

only in Crabbe bonds? How much interest would he earn each year if he

invested only in Malfoy bonds?

d$.$ Assume that Mark will reinvest all the interest he receives as it is paid, and his

rate of return on reinvested interest will be $10\%.$ Calculate the total dollars that

Mark will accumulate over five years if he invests in Crabbe bonds or Malfoy

bonds. Your total dollar calculation will include the interest Mark gets, the

principal he receives when the bonds mature, and all the additional interest he

earns from reinvesting the coupon payments that he receives.

e$.$ The bonds issued by Crabbe and Malfoy might appear to be equally good

investments because they offer the same yield to maturity of $7\mathrm{.}5\%.$ Notice,

however, that your answers to part $d$ are not the same for each bond, suggesting

that one bond is a better investment than the other. Why is that the case?
