Answer 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)
