You start with the initial amount of rain (-11) and then work through the problem. The first part has you adding 1/2 seven times so you end up with -11 + 1/2(7) = -7.5. However it then drops 2 1/4 for three months so you do -7.5 - 2 1/4(3) = -14 1/4

$\ \textgreater \$ means you shade the part above the line, and $\ \textless \$ means you shade the part under the line.

If it has an equal bar under it, like this: $\leq or \geq$ , then you also shade the line, by making it solid instead of dotting it.
