Answer:

The correct option is (B) $365,530.

Explanation:

In this problem we need to determine the future value, i.e. the amount at the retirement age.

The formula to commute the future value is:

[tex]\\ FV=A[\frac{(1+r)^{n}-1}{r}][/tex]

Here,

A = annual investment = $5,000

r = interest rate = 8%

n = number of periods = 25

The future value is:

[tex]\\ FV=A[\frac{(1+r)^{n}-1}{r}]\\=5000\times[\frac{(1+0.08)^{25}-1}{0.08}]\\=365529.699\\\approx365530[/tex]

Thus, the amount of money the engineer will have in the account at retirement is $365,530.
