Adriana opened a savings account and deposited $300.00 as principal. The account earns 6% interest, compounded annually. What is the balance after 9 years? Use the formula A=P1+ r n nt, where A is the balance (final amount), P is the principal (starting amount), r is the interest rate expressed as a decimal, n is the number of times per year that the interest is compounded, and t is the time in years. Round your answer to the nearest cent.
