This can be answered using the following formula for interest:
Let:
F = future value
P = principal value
n = interest period (n = 3)
i = interest percentage
F = P(1 + i)^n
Substituting the given values, we arrive at the following:
F = 3300(1 + 0.04)^3
F = 3712.05
Therefore, after 3 years, the balance in the account will be $3712.05
