Answer:
3.5%
Step-by-step explanation:
the yield to maturity of a zero coupon bond is calculated using the following formula:
YTM = (face value / current market value)¹/ⁿ - 1
YTM = ($100 / $70.89) ¹/¹⁰ - 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)¹⁰ = $99.997 ≈ $100
