Explanation:
We sovle for the PV of the annuity of 70,00 during 8 years discounted at 8%
[tex]C \times \frac{1-(1+r)^{-time} }{rate} = PV\\[/tex]
C 70,000.00
time 8
rate 0.08
[tex]70000 \times \frac{1-(1+0.08)^{-8} }{0.08} = PV\\[/tex]
PV $402,264.7261
To know the value of the outstanding dbet we can repeat this formula changing the values for time
t = 7 Â $364,445.9041
t = 6 Â $323,601.5765
t = 5 Â $279,489.7026
t = 4 Â $231,848.8788
t = 3 Â $180,396.7891
t = 2 Â $124,828.5322
t = 1 Â $64,814.8148
