Answer:
B, $305.11
Explanation:
since it is in annual interest, 36 months = 3 years.
use the formula for simple interest, which is x = Prt
278 * 0.0325 * 3 = 27.105
that is the interest that you gained.
then, add the original amount that you had, which was 278.
27.105+278 = 305.105
this rounds to $305.11, which is answer choice B
