Hey everyone,

I'm stuck on the last 2questions of the 4.2 homework

The question was:

Find the future value and interest earned if

$8804.56

is invested for

7

years at

5%

compounded semiannually.

We had to findthe future value when interest is compounded semiannually which I answered correctly as $12440.61, but I cannot figure out how to solve the interest earned approximately. I used the formula but I'm still struggling can anyone explain where I'm going wrong?
