Thank you so much.
I had already calculated this exercise, but I thought that I did it wrong, however I get same result as you.
Reason for thinking I had done it wrong is that, my teacher have answered this exercise before and the second part is different than mine and yours. I dont understand how she get the value for second part? It's so confusing
