(a) Sea level is \(0\), therefore the elevation of city (A) is \(-96\), and the elevation of city (C) is \(-24\). For this part we do not need the elevation of city (A). The elevation of city (D) is \(\frac{1}{4}\) of city (C). The key word is OF! Of means to multiply. Therefore we have the expression\(-24\cdot\frac{1}{4}\).

 

(b) Part b is fairly simple. All you have to do is compute \(-24\cdot\frac{1}{4}=-6\). As for explaining why it's negative we go back to how a negative times a positive is a negative. 

 

 

This wasn't a very challenging problem. Are you sure you couldn't have solved it?

Thanks for your great answer keylime.

 

I would like to suggest that you do not use sentences like 

"This wasn't a very challenging problem. "

What is easy for you may well be very difficult for someone else.

You should put EP’s post back. It’s the best post in the past week! I posted a copy on #2 

You should put your post back too!  It’s not as funny but it’s true!

It was not EPs post. EP has assured me he did not write it.

For the benefit of others,  EP and Nickolas are both being trolled.
