Final answer:
Monica will have $636 in her savings account at the end of 2 years.
Step-by-step explanation:
To calculate the amount of money Monica will have in her savings account after 2 years, we can use the simple interest formula: Interest = Principal x Rate x Time. In this case, the principal is $600, the rate is 3%, and the time is 2 years.
So, the interest earned after 2 years is: $600 x 0.03 x 2 = $36.
To find the total amount of money, we add the interest to the principal: $600 + $36 = $636.
Therefore, Monica will have $636 in her savings account at the end of 2 years.
