For this sort of problem, you need to be familiar with prefixes.
So:
megabyte =
bytes
kilobyte =
bytes
and a regular byte would just be 
Now, you will need to do a conversion:

I'm going to explain this just in case, but we convert megabytes to regular bytes in the first half by using the information I gave you above. (In one megabyte, there are
bytes!)
In the second fraction thought, remember one kilobyte is
bytes. However, you usually only see one of each thing on the bottom of fractions, so you need to add a negative sign to the 3. (technically you could just do
, but I think it is more correct to do write it out how I did).
*** They do equal the same thing though! Do whichever way is easier for you!
Now, your answer should be:
kilobytes (1000 kilobytes)

$500 - $200 = $300 dollars left.
$300 divided by $10 = 30 weeks.
