While you can't say that there are an infinite number of elements to the solution set given the restriction that the coordinates of the solution ordered pairs must be in of a dollar increments, there are a great many possibilities. You need more information to solve this problem. Don't write back to me as I probably won't get to this until tomorrow or the next day if you do. Repost the problem with all of the information.
