Answer:
How should she compute her required annual investment?
$ 36.987
Step-by-step explanation:
With the present value formula we can calculate how she has to invest today to get $45,000 at the end of the 5 years, with a compounded rate of 4%.
Principal Present Value = F / (1 + r)^t
In this case we have the future value and we need to find the present value that we have to invest to get the money expected.
Principal Present Value = 45,000 / (1 + 4%)^5 = $36,987
If we invest today $36,987, with a compounded interest rate of 4% we get at the end of the period, 5 years, the total sum of $45,000.
