Maggs invest 10,250 at a rate of 9% compounded weekly to the nearest whole dollar find the value of the investment after 7 years

OK, I am assuming that this interest rate is to remove money and not add. I am also assuming you don't need to round to the nearest dollar till the end.

Meaning:

10,250 x 9% = 922.5 then, 10,250 - 922.5 = 9,327.50

9,327.50 x 9% = 839.48, then 9,327.50 - 839.48 = 8,487.52

8,487.52 x 9% = 763.88, then 8,487.52 - 763.88 = 7,723.64

7,723.64 x 9% = 695.13, then 7,723.64 - 695.13 = 7,028.51

7,028.51 x 9% = 632.57, then 7,028.51 - 632.57 = 6,395.94

6,395.94 x 9% = 575.63, then 6,395.94 - 575.63 = 5,820.31

5,820.31 x 9% = 523.83, then 5,820.31 - 523.83 = 5,296.48

Once the annoying math is out of the way, all we have to do is round it.

5,296.48 = 5,296 (The dollar doesn't go up since .48 is not half nor greater than a dollar.)

Meaning your answer is $5,296. Now I'm not entirely sure if that is correct. It would help if I knew the entire situation of the problem, like is this rate of 9% adding or subtracting, or do you mean round the dollar during every part or just in the end, etc. SO I did what I could based on the info I had.
