A woman arranging high heels on a shelf in an upscale shoe store If you're working on commission, you'll need a good understanding of percentages.
Janet is excited to start her new job selling shoes at an upscale department store. The only thing she's a little nervous about is that her pay will be based on commission. She needs to make sure she'll earn enough money to cover her budget, so she wants to figure out how much she'll have to sell to cover her costs of living. In order to do this, Janet needs to understand how to work with percentages in real-life situations.
