Have you got a mathematical mind?

     Are you good at maths? I've got a question that at first sight is very easy. However, I'm not quite sure of the right answer and I'd like that somebody with mathematical abilities helped me to find the solution.
     Last week I needed a pen and a piece of paper. I went to the stationner's and asked for them. The total price amounted to 1.10 €. Now, my question is: if the sheet cost 0.10 €, how much more did the pen cost than the piece of paper?
