Final answer:
To compare the returns of Account 1 and Account 2, calculate the final amount in each account after 3 years using compound interest. Compare the amounts to determine the account with a higher return and calculate the difference in returns.
Step-by-step explanation:
To compare the returns of Account 1 and Account 2, we need to calculate the final amount in each account after 3 years using compound interest.
For Account 1: Principal amount = $500, Interest rate = 1.2% compounded monthly.
The formula to calculate the final amount in Account 1 is: Final Amount = Principal x (1 + (Interest Rate/100))^Number of times interest is compounded.
For Account 2: Principal amount = $500, Interest rate = 1.3% compounded semiannually.
The formula to calculate the final amount in Account 2 is the same as Account 1, but with a different interest rate.
After calculating the final amounts in both accounts, we compare them to determine the account with a higher return and calculate the difference in returns.
