Transcribed Image Text:### Understanding Price Elasticity of Demand
The diagram presented here is a graphical illustration used to explain the concept of price elasticity of demand using two different demand curves: \( D_{\text{Flat}} \) and \( D_{\text{Steep}} \). Let's break down and understand the elements of this graph.
#### Graph Explanation
1. **Axes and Labels**:
- The **horizontal axis (Q)** represents the quantity demanded.
- The **vertical axis (P)** represents the price level.
2. **Curves**:
- **Supply curve (S)**: This is depicted in red, indicating the relationship between the price and the quantity supplied.
- **Flat Demand curve (\( D_{\text{Flat}} \))**: This is one of the two demand curves shown in blue, representing a more elastic demand.
- **Steep Demand curve (\( D_{\text{Steep}} \))**: This is the other demand curve shown in blue, representing a more inelastic demand.
3. **Points and Lines**:
- **Point A**: This is the initial equilibrium point where the quantity demanded equals the quantity supplied at \( Q_1 = 100 \) and \( P_1 = 10 \).
- **Point B**: This denotes a new point on the \( D_{\text{Flat}} \) curve at \( Q_2 = 90 \) and \( P_2 = 12 \).
- **Point C**: This denotes a point on the \( D_{\text{Steep}} \) curve at a lower quantity \( Q_3 = 50 \) and the same higher price \( P_2 = 12 \).
4. **Price Levels**:
- **Initial Price (\( P_1 \))**: $10
- **New Price (\( P_2 \))**: $12
5. **Quantities**:
- **Initial Quantity (\( Q_1 \))**: 100 units
- **Quantity for \( D_{\text{Flat}} \) (\( Q_2 \))**: 90 units
- **Quantity for \( D_{\text{Steep}} \) (\( Q_3 \))**: 50 units
