Transcribed Image Text:**Title: Understanding Demand and Supply Curves in Market Economics**
An economist estimates that a market has a **demand curve** represented by the equation \( P = 34 - (1.13) Q \) and a **supply curve** represented by the equation \( P = 8.5 + (1.02) Q \). These curves are illustrated in the graph below.
**Graph Explanation:**
The graph features:
- **Axes:**
- The vertical axis represents the price (\( P \)).
- The horizontal axis represents the quantity (\( Q \)).
- **Demand Curve (Blue Line):**
- Slopes downward from left to right, indicating that as price decreases, the quantity demanded increases.
- **Supply Curve (Red Line):**
- Slopes upward from left to right, indicating that as price increases, the quantity supplied increases.
- **Equilibrium Point (E):**
- The intersection of the demand and supply curves.
- At this point, the equilibrium price (\( P_e \)) and equilibrium quantity (\( Q_e \)) are determined.
**Market Analysis:**
By her estimations, if the price in the market is currently at a certain level, then there should be a shortage on the market of a specific number of units. Choose the correct price and shortage combination from the options below:
- A. $12.10; 15.85
- B. $20.6; 17.54
- C. $30.00; 11.86
- D. $9.00; 7.52
**Conclusion:**
This exercise helps in understanding how demand and supply curves interact to determine the market equilibrium and how variations in price can lead to surpluses or shortages.
