Answer:
The formula for compound interest is A = P(1 + r/n)^(nt), where A is the final amount, P is the initial principal, r is the interest rate, n is the number of times the interest is compounded per year, and t is the time in years.
In this case, P = $100, r = 9% = 0.09, n = 1 (compounded annually), and t = 16. We want to find A.
A = 100(1 + 0.09/1)^(1*16)
A = $397.42
Therefore, Javae will have $397.42 in his account on his 30th birthday. The answer is option D.
