It's been a while since I've posed a riddle; so I'm back with a simple one! I hope you all enjoy, and as always, good luck!
Sally went to the farmer's market, with her daily $100\,\text{lbs}$ of potatoes. After sitting in the sun all day and no one showing interest, she decided to pack up and go home. But, she noticed something rather odd...
Sally only had $50\,\text{lbs}$ of potatoes left. But how? No one even glanced at her stand.
What happened? Make sure you explain the drastic difference.
