Final answer:
To find the amount of interest earned, use the formula for simple interest: Interest = Principal * Rate * Time. Plugging in the given values, the interest earned is $360.
Step-by-step explanation:
To find the amount of interest earned in an account with an initial deposit of $800 for 15 years at an interest rate of 3%, you can use the formula for simple interest:
Interest = Principal * Rate * Time
In this case, the principal is $800, the rate is 3% (or 0.03), and the time is 15 years. Plugging these values into the formula:
Interest = $800 * 0.03 * 15
Therefore, the amount of interest earned is $360.
