Okay, to solve this problem we need to understand the difference between simple and compound interest. I'm assuming you know, so I'll just repeat. Simple interest is just what it sounds like; simple. As time goes on, it adds 4% each year (assuming it is annual) to the deposited amount. Compound interest is another story. Compound interest adds the 4% to the deposited amount... Plus the interest already added. So obviously, an account with compound interest would get more. I'll leave you with that, try to solve the question and I'll check your work.

B?

Close, but the answer would be A. Elsie is the one who earned more, so she would have an account with compound interest. Very common mistake.
