You purchased a zero-coupon bond one year ago for $279.83. The market interest rate is now 9 percent. Assume semiannual compounding. If the bond had 15 years to maturity when you originally purchased it, what was your total return for the past year

4.20%

Explanation:

The zero-coupon bond now 14 years left before maturity,which means that we need to compute the price with 14 years maturity and interest rate of 9% per year in order to determine the total return on the bond over a year period.

Price of the bond=present value of face value of $1000

9% annually while 4.5% is the semiannual yield

the bond has 28 semiannual periods in 14 years

price of the bond today=$1000/(1+4.5%)^28=$291.57  

return over a year=($291.57-$279.83)/$279.83=4.20%

being born in poverty would limit the people's chances, opportunities and benefits.

this happen because of several things, such as:

- poor people tend to gain less access to good education and nutrition. this mean that their chance to obtain high paying jobs would also be limited.

- poor people tend to socialize with other poor people while the rich tend to socialize with other rich people. this means that simply throguh their social circle, rich people would have more business opportunities compared to the poor people.

- rich people tend to have more capital in their disposal. this would benefit them in business since it is far easier for them to fund their business operation compared to poor people.
