Answer:
We should make monthly deposits of 572.90 dollars to achieve the 2,000,000 dollars in 40 years
Explanation:
We have to calculate the monthly annuity to achieve 2,000,000 in 40 years (which is 40 x 12 = 480 months)
[tex]FV \div \frac{(1+r)^{time} -1}{rate} = C\\[/tex]
FV 2,000,000
time 480
rate 0.006666667 ( 0.08 / 12 month per year)
[tex]2000000 \div \frac{(1+0.0066667)^{480} -1}{0.006666667} = C\\[/tex]
C $ 572.900
