Using an exponential function, it is found that the value of David's Investment will be at least $415 after a period of 20 years.
<h3>What is an exponential function?</h3>
An increasing exponential function is modeled by:

In which:
- A(0) is the initial value.
- r is the growth rate, as a decimal.
In this problem, the initial value and the growth rate for his investment are given by:
A(0) = 230, r = 0.03.
Hence, the value after t years is given by:

Then, the value will be of at least $415 when:
