  1. What is your question?
    Are you finding the amount after some time?
    You gave no time period.

    You gave the simple interest formula and the compound interest formula, state which investment fits each method.

    Please restate your question.

  3. Marta has $6000 to invest. She puts x dollars of this money into a savings account that earns 2% interest per year. With the rest, she buys a certificate of deposit that earns 4% per year. I'm guessing it's monthly. I need to know the equation for the amount of money T Marta will have in one year. however, as I'm reading it, I'm not sure whether you have to use te compound interests.
    Then there's a separate question saying: Suppose at the end of one year, Marta has a total of $6210. How much money did Marta invest in each amount (savings acount and certificate of deposit)
