Half-baked ideas

Imagine you own the Risky Business Bakery, a small bakeshop in need of some help. You work hard, and your profits are declining. You look back through your sales data to determine how you can increase sales without significantly increasing costs.

You will start by determining which items sell best and which days are busiest. Then you'll see how tweaking prices on those days might increase or decrease sales and demand.
