A company produces and sells copies of an accounting program for home computers. The total weekly cost (in dollars) to produce \(x\) copies of the program is \(C(x)=8x+500\). Find its weekly profit if the total revenue obtained from selling all \(x\) programs is \(R(x)=35x-0.1x^2\). How much profit will the company make if it produces and sells \(100\) programs a week? That is, find \(P(100)\).
