Question 1178255
<br>
Your answer to the first question is right; and you show the correct calculations.<br>
Your answer to the second question is not right; and you DON'T show your calculations, so we don't know what you did wrong.<br>
If you want to learn from using this forum, then re-post showing HOW you got your second answer and we can help you with learning the right way.<br>
The point of this response is that on the first part you did exactly what we ask you to do: show your work.  It's unfortunate you didn't do the same thing for the second part.<br>
