The Lo Sun Corporation offers a 5.1 percent bond with a current market price of $872.50. The yield to maturity is 6.19 percent. The face value is $1,000. Interest is paid semiannually. How many years until this bond matures

21.12 years

Explanation:

The nper excel function can be used to compute the number of years the bond would mature as shown below:

=nper(rate,pmt,-pv,fv)

rate is the semiannual yield to maturity which is 6.19%/2

pmt is the semiannual coupon payment=5.1%/2*$1000=25.5

pv is the current market price of $872.50

fv is the face value of $1000

=nper(6.19%/2,25.5,-872.50,1000)= 42.24  

The  42.24  implies the number of six-month intervals the bond has

number of years= 42.24/2=21.12

the answer would be voluntary exchange -

"the act of buyers and sellers freely and willingly engaging in market transactions. moreover, transactions are made in such a way that both the buyer and the seller are better off after the exchange than before it occurred."

hope this : )
