(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?
