Answer:
 $104.49
Step-by-step explanation:
The future value of the account is given by the formula ...
 FV = P(1 +r)^t
The interest earned is the difference between that future value and the original amount deposited.
 I = FV -P
__
For the given investment, rate, and time, we find the interest to be ...
 I = $650((1 +0.0125)^12 -1) = $650(0.160755) = $104.49
Mr. Vance's account will have earned $104.49 in interest at the end of 12 years.
