Math class is tough
"Picture this: You're at the supermarket trying to find the best deal on AAA batteries for your flashlight, so you check the price labels beneath each pack. Sounds pretty straightforward, right? But how can you tell which pack is cheaper when one is priced per battery and one is priced per 100?"

Hmmm. Move the decimal point 2 places?
That's an easy one. But how about cases where different brands give
price per lb, price per oz, price for each, and price for servings?
What if some batteries have different life expectancies?
Ha!!! Good one! I'm embarrassed that I didn't see that one coming. :(
Anonymous 2:32pm: sure. I'm not ragging on unit pricing specifically, just CR's example.
