Elastic and Inelastic Demand Examples: Everyday Products

📚 Quick Study Guide

• 📏 Elastic Demand: Occurs when a change in price significantly affects the quantity demanded. Consumers are sensitive to price changes.
• 📉 Inelastic Demand: Occurs when a change in price has little effect on the quantity demanded. Consumers are not very sensitive to price changes.
• 🧮 Price Elasticity of Demand (PED) Formula: $PED = \frac{\% \ Change \ in \ Quantity \ Demanded}{\% \ Change \ in \ Price}$
• 💡 Elasticity > 1: Elastic demand.
• 🔑 Elasticity < 1: Inelastic demand.
• ⛽ Necessities: Tend to have inelastic demand (e.g., gasoline, medicine).
• luxury Goods:** Tend to have elastic demand (e.g., designer clothing, fancy coffee).
