Math of investment

..pls give me a solution.. Thanks..

You love your homework so much you asked a question about it in love and relationships?

Oh, and just put 30,007

do you mean you start with 30 000?

Then the solution is.

30 000 X 7% interest for the whole year X 9/12 months (or you can use days) =
1575 interest.

Thus your capital amount will be 31575
