Days Off

My friend Jen is moving across the country soon, so in preparation, we hold a yard sale. She needs to divest herself of some of her dead mom's former possessions, and I'm trying to unload some items I just haven't used recently, like my adhesive glow-in-the-dark stars and my Avenging Unicorn Play Set. As the day gets longer, we grow increasingly desperate to get rid of every single item we can. Bonus: see if you can catch the  math error.
