A = P(1+r)^t where P is the principal (starting) amount, r is the rate of interest, and t is time. Knowing this, plug in your values:
A = 3,000(1+0.025)^4 < this is what your equation should look like. Once you enter this into a calculator, you should get an answer of $3,311.438672. Round, and you'll be finished.
Answer: The final balance on the account will be $3,311.44
