a. The interest earned will be $36.
b. The account balance will be $336.
Step-by-step Explanation:

4% of $300 =
Step 2:
So for every year, the interest of $12 is added into the account. To calculate total interest we multiply this interest amount and the number of years.
So after 3 years
So account balance after 3 years .
So the interest earned is $36 and the account balance is $336 after three years.
