Use the cash flows of a portfolio of the following three bonds to calculate the yield to maturity of the portfolio. Each bond has a face value of $1,000. Use the cash flows and yield to maturity to calculate the duration of the portfolio.
a. three-year zero-coupon bond with 5% yield,

c. seven-year zero-coupon bond with 6% yield.
Verify your portfolio duration calculation using the weighted average of the individual bond durations.
