So, I am actually good at this. for this problem Sea level is , therefore the elevation of city (A) is , and the elevation of city (C) is . For this part we do not need the elevation of city (A). The elevation of city (D) is  of city (C). The key word is OF! Of means to multiply. Therefore we have the expression.

(b) Part b is fairly simple. All you have to do is compute . As for explaining why it's negative we go back to how a negative times a positive is a negative.
