A $3300 principal earns 4% intrest, compounded annually. After 3 years, what is the balance in the account.

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
