It seems newbies aren't allowed to send a picture here because I did my calculations in my notebook as it would have been easier for me to drop a picture of my calculations. I may be wrong though with my answer but am delighted to participate.
I would be glad to see your calculations! Drop them in
talkimg and post them as a link (since you're prohibited to posting images).
here is my calculation, i hope you can see it clearly.
