Final answer:
Savings Account B earned the most interest after one year.
Step-by-step explanation:
To determine which savings account earned the most interest after one year, we can calculate the interest earned by each account using the formula:
Interest = Principal x Rate
For Account A: Interest = 1500 x 0.035 = $52.50
For Account B: Interest = 1400 x 0.04 = $56.00
Therefore, Account B earned more interest after one year, with a total of $56.00.
