Your **Lemonade Stand Supply & Demand Simulator** is ready! Here's what's in it:

**Core Gameplay Loop:**
- **Set Price** - Slider from $0.25 to $5.00 per cup. Higher prices = lower demand (price elasticity)
- **Set Supply** - Choose how many cups to make (costs $0.25+ each in ingredients)
- **Watch the Day** - Customers walk up based on calculated demand; if you run out, latecomers leave unhappy
- **Review Results** - See revenue, costs, waste, and profit. A supply/demand chart tracks your history across days

**Economics Model:**
- Demand follows an exponential decay curve based on price (realistic price elasticity)
- **Weather** affects demand (hot = more thirsty customers, rain = fewer)
- **Random events** like parades, school letting out, or competing stands shift demand
- Ingredient costs increase over time (inflation)
- Unsold cups = wasted money (overproduction penalty)
- Undersupply = lost sales (missed opportunity)

**The Supply & Demand Tension:**
- Price too high? Demand drops and cups go unsold
- Price too low? You sell out but profit margins shrink
- Too much supply? Waste eats your profits
- Too little supply? You miss potential revenue

**Next Ideas:**
1. **Upgrade System** - Invest profits in better signage (attracts more customers), a cooler (reduces waste), or premium lemons (charge more)
2. **Competitor AI** - Add rival lemonade stands that dynamically adjust their prices, forcing you to adapt your strategy
