    Dear David and Alexa

    I‘ve read your calculation example and tried to solve it. I think you did a quite good job there. The example is realistic and could occur to us in real life. I have to admit though that I had a hard time trying to solve it and in the end came up with a completely wrong answer.

    Best Wishes,
    Leandro
