Answer:
It will require deposists for 11.79 years
Explanation:
We need to solve for the time at which an ordinary annuity of 134,000 each quarter at 1.35% rate generates a future value of 1,700,000
[tex]C \times \frac{(1+r)^{time} -1}{rate} = FV\\[/tex]
C $134,000.00
time n
rate 0.0135
FV $17,000,000
[tex]134000 \times \frac{(1+0.0135)^{n} -1}{0.0135} = 1,700,000\\[/tex]
we rearrenge and solve as we can:
[tex](1+0.0135)^{n}= 1 + \frac{1700000\times0.0135}{134000}[/tex]
[tex](1+0.0135)^{n}= 1.17126866[/tex]
Then use logarithmics properties to solve the equation:
[tex]n= \frac{log 1.17126866}{log(1+0.0135)[/tex]
n = 11.78905103
