Word problem.

Matthew is a composer. Today, Matthew received his first substantial royalty check, which came with a breakdown of how well his two pieces sold over the past two years. Matthew is not sure how proper it is to divulge those sales numbers, but he can give you these facts:

* Matthew was expecting the arrangement to outsell the original piece by 325 copies.

* The arrangement sold 120 fewer copies than Matthew expected it to. However, the original piece sold 225 more copies than Matthew expected it to.

* Together, Matthew was expecting to sell 575 copies.

* Matthew was wearing blue as he opened the envelope containing the royalty check.

Please solve for the number of copies Matthew actually sold of each piece. Keep in mind that not all information given in the word problem is relevant to the solution.
