Give the others have already answered the question for you, let me give you three tips on how to nail this question next time :)
1) Question first - read the immediate question first (i.e. total impact of effects on annual sales). Skip the context, skip the charts, read the one sentence that asks you the question that matters. This helps you frame your mindset and pull out only the information that matters.
2) Block out the charts - think about what information you need before you read the charts. What #s would you need and how would you use/multiply them? Again, this keeps you focused on what actually matters once you look at the charts.
3) Answer Plug-in/Elimination - Read the answers early on. First, quickly figure out which ones clearly don't make sense (and cross them out). Second, plug and play the answers they've provided. In some cases you can back-solve the answer. To summarize: Test the answers provided instead of doing all the work to find the answer!
