Answer:
The bond will yield 4% per year
Explanation:
We have to look the bond return after three years:
year 1 will be the current year yieled
year 2 is 1 year ahead
year 3 is 2 year ahead
year 4 is three year ahead.
And from this rate we also consider the next rate as it is a two year bond:
[tex](1+r)^2 = 1.04 \times 1.04\\1 + r = \sqrt{1.0816}\\r = 1.04 - 1[/tex]
r = 0.04 = 4%
