Final answer:
Beatrice will earn $270.90 in interest over 12 years.
Step-by-step explanation:
To find the amount of interest Beatrice will earn, we can use the formula for simple interest: Interest = Principal x Rate x Time. In this case, the principal (the initial amount deposited) is $525, the rate is 4.3%, and the time is 12 years.
Using the formula, the interest earned would be: Interest = $525 x 0.043 x 12 = $270.90.
Therefore, Beatrice will earn $270.90 in interest over 12 years.
