Providing numerical justification

Let’s assume that before international trade opens up, Russia is at a point on its production possibility curve (PPC) where it produces 40 apples and 40
computers. Once trade opens up, the price of a computer becomes two apples. In response, Russia moves along its PPC to a new point where it is producing
50 computers and 20 apples. Is Russia now better off? Explain by providing numerical justification.
