Really not sure sorry, if you don't know how to do piecewise functions, you could look at this video: https://www.youtube.com/watch?v=hy0N-90gCu0

Do you know if the answer is $2520 or $5250?

You know its 200 per project when 5 or less projects are done, 250 per project when more than 5 projects but 10 or less projects are done and 350 per project when more than 10 are done. 
When more than 10 projects are done then you have 350 (x-10). The x-10 comes from the fact that when he does more than 10 projects are done.

Here is the piece wise function based on the information given:
|dw:1452931495523:dw|

You should be able to find the answer from here.
