Answer:
Using the compounding formula we can calculate the amount that I will earn by calculating the difference between the Future value of the investment and the amount invested.
Step 1 Find Future Value
FV = Present Value * (1+r)^n
So
Future Value = $750,000 * (1+9%)^1
FV = $817,500
Step 2 Find the Difference between he Future value of the investment and the amount investment
And the amount invested is $750,000
The amount I can withdraw = FV less The amount invested
The amount I can withdraw = $817,500 - $750,000 = $67,500
So the amount that I will earn and I can withdraw annualy is $67,500.
