Answer:
first case: $834,290.82
second case: $493,482
Because the 10 years capitalized for more time the magic of compounding interest can do his work
Explanation:
first case:
and annuity of 3,000 for 10 years
and then a lump sum for 30 years:
[tex]C \times \frac{(1+r)^{time} -1}{rate} = FV\\[/tex]
C 3,000
time 10 year
rate 10% = 0.1
[tex]3000 \times \frac{(1+0.1)^{10} -1}{0.1} = FV\\[/tex]
FV $47,812
[tex]Principal \: (1+ r)^{time} = Amount[/tex]
Principal 47,812.00
time 30.00
rate 0.10000
[tex]47812 \: (1+ 0.1)^{30} = Amount[/tex]
Amount 834,290.82
Second case:
annuity of 3,000 for 30 years:
[tex]C \times \frac{(1+r)^{time} -1}{rate} = FV\\[/tex]
C 3,000
time 30
rate 0.1
[tex]3000 \times \frac{(1+0.1)^{30} -1}{0.1} = FV\\[/tex]
FV $493,482
