Using the future value formula, it is found that $546,148,903,191,724.25 will be in Devon's account.
It is given by:
[tex]V(n) = P\left[\frac{(1 + r)^{n-1}}{r}\right][/tex]
In which:
In this problem, the parameters are as follows: P = 587, r = 0.0525, n = 40 x 12 = 480.
Hence:
[tex]V(n) = P\left[\frac{(1 + r)^{n-1}}{r}\right][/tex]
[tex]V(480) = 587\left[\frac{(1 + 0.0525)^{480-1}}{0.0525}\right][/tex]
[tex]V(480) = 546,148,903,191,724.25[/tex]
$546,148,903,191,724.25 will be in Devon's account.
