Final answer:
To calculate the interest earned in a simple interest bank account, multiply the principal by the interest rate and the time. In this case, Jane earned $240 in interest over three years.
Step-by-step explanation:
To calculate the interest earned in a simple interest bank account, we use the formula:
Interest = Principal * Rate * Time
In this case, Jane deposited $2,000 in the bank account at an interest rate of 4% for three years. Plugging in the values into the formula, we get:
Interest = $2,000 * 0.04 * 3 = $240
Therefore, Jane earned $240 in interest over the three-year period.
