We use the compound interest formula A = P(1 + r/n)^nt, where A is the ending amount, P is the starting amount (P = $3,000), r is the interest rate (r = 0.06), n is the number of times the interest is compounded per year (n = 12), and t is the number of years (t = 1).

The amount of money in the account, rounded to the nearest dollar, at the end of one year is:

A = 3000(1 + 0.06/12)^12 = 3000(1.005)^12 = $3,185
