Narrator:  Carla is shopping for some new clothes with the money she got for her birthday.  

Carla: So many choices…but if I don’t spend my birthday money today, these sales will be gone!

Carla: Buy 2 Get 1 Free. 40% off everything. Buy 1 get one half off. Why do they have to make this stuff so confusing?  There’s got to be a way to figure this out…

Carla: Eeny, meeny, miny, moe.  Oh, that won’t work!  I’ll do Buy 2 – Get 1 Free. You can’t beat free!

Narrator:  Maybe you can. Before you head to the cash register, Carla, you’d better check your math. 

(Sound of cash register: Ka-ching!)
