Answer-
You need to deposit $337.62 each month, to reach this goal.
Solution-
We know that,
[tex]\text{FV of annuity}=P[\frac{(1+r)^n-1}{r}][/tex]
Where,
P = periodic payment
r = rate per period
n = number of period
Here,
[tex]FV\ of\ annuity=2,500,000,\\\\P=?,\\\\r = 9\%\ annually=\frac{9}{12}\%\ monthly=\frac{9}{1200}\ monthly\\\\n=45\ years=45\times 12=540\ months[/tex]
Putting the values,
[tex]\Rightarrow 2500000=P[\frac{(1+\frac{9}{1200})^{540}-1}{{\frac{9}{1200}}}][/tex]
[tex]\Rightarrow P=\frac{2500000}{[\frac{(1+\frac{9}{1200})^{540}-1}{{\frac{9}{1200}}}]}[/tex]
[tex]\Rightarrow P=\frac{2500000}{\frac{56.5365-1}{0.0075}}[/tex]
[tex]\Rightarrow P=\frac{2500000}{\frac{55.5365}{0.0075}}[/tex]
[tex]\Rightarrow P=337.62[/tex]
