Question

Emma is saving money for college. She has $800 and wants to deposit it into 2 different savings accounts. She decides to deposit $500.00 into an account, Account I, which earns 2.5% annual simple interest. She will then deposit $300 into an account, Account II, which earns 2 1/4%
 interest compounded annually.
If Emma makes no other deposits or withdrawals, what is the total amount of money she will have at the end of 3 years?

I have to show my work for this question, but I'm not sure how to do it.
