Answer:

Calculate the Macaulay duration of Annuity B at the time of purchase is 1.369.

Step-by-step explanation:

First, we use 0.93 to calculate the v which equals 1/(1+i).

\frac{0+1*v+2v^{2} }{1+v+v^{2} } = 0.93

After rearranging the equation, we get 1.07v^{2} + 0.07v - 0.93=0

So, v=0.9

Mac D: \frac{0+1*v+2*v^{2}+ 3*v^{2} }{1+v+v^{2}+ v^{3} }

After substituting the value of v, we get Mac D = 1.369.
