According to the Austin News, Facebook made around $800,000,000 in advertising revenue. Personally I hate Facebook Ads. With the passion of 100 burning stars. So here's a question we kicked around in class:
Facebook makes $800,000,000 in advertising. Suppose they offer to have Facebook free of ads for $100 per user. How many people would have to sign up for the Ad-free version to make this a good business offering? Write an inequality, solve and graph.
Remember an Inequality is a case of "x < 10" or "300 + y > 600".
A great way to engage your student would be to bring this problem and not only talk about the actual math, but also why the idea of a good business offering requires it to be one value "Greater than" the other.
