Answer:
3.5%
Explanation:
the yield to maturity of a zero coupon bond is calculated using the following formula:
YTM = (face value / current market value)ยน/โฟ - 1
YTM = ($100 / $70.89) ยน/ยนโฐ - 1 = 3.5%
the way you can check if your calculations were correct is to find the future value of the bond using the YTM = $70.89 x (1 + 3.5)ยนโฐ = $99.997 โ $100
