In this video, we'll use a real world precalculus example to show why learning math ISN'T pointless! For your calc ab exam, you may see a math problem like this involving compound interest and properties of logarithms. Here, we'll tie what you're learning to a modern day dilemma: the rising cost of living and how you can use math to GET A RAISE at your job!!!!

We'll setup a real world example problem where we're compounding inflation monthly and we'll need to solve the expression to see at how many months, your cost of living exceeds your paycheck. Hope you enjoy this video!
