Answer:
PV $61,399.0165
Explanation:
First, we solve for the present value of the annuity:
3rd year > Annuity Start 25th year end
<-----/----/----/----/----/----/----/----/----/......----/----/----/----/----/---->
^ Present day
[tex]C \times \frac{1-(1+r)^{-time} }{rate} = PV\\[/tex]
C 6,800.00
time 22 years (25 - 3)
rate 0.07
[tex]6800 \times \frac{1-(1+0.07)^{-22} }{0.07} = PV\\[/tex]
PV $75,216.4354
Now, as this is 3 years from now so we make an additional discount from this lump sum:
[tex]\frac{Maturity}{(1 + rate)^{time} } = PV[/tex]
Maturity $75,216.4354
time 3.00
rate 0.07000
[tex]\frac{75216.4353825748}{(1 + 0.07)^{3} } = PV[/tex]
PV 61,399.0165
that would be the value of the annuity today.
