Aperson invests $4000 at 2% interest compounded annually for 4 years and then invests the balance (the $4000 plus the interest earned) in an account at 8% interest for 7 years. find the value of the investment after 11 years. (hint: you need to break this up into two steps/calculations. be sure to round your balance at the end of the first 4 years to the nearest penny so you can use it in the second set of calculations.)
