Q11

An economist estimates that a market has a **demand curve** of the form P = 38 - (1.27)Q and a **supply curve** of the form P = 7 + (1.78)Q. (See the curves graphed in the figure below.) She estimates that if the market price is P = ____ then there will be an excess product (a surplus) on the market of ____ units.

### Graph Description

- **Axes**: The vertical axis represents the price (P), and the horizontal axis represents the quantity (Q).
- **Curves**: 
  - The **demand curve** is shown as a downward-sloping line in blue, indicating a negative relationship between price and quantity demanded.
  - The **supply curve** is represented by an upward-sloping line in red, indicating a positive relationship between price and quantity supplied.
- **Equilibrium**:
  - **Pe** and **Qe** indicate the equilibrium price and quantity where the supply and demand curves intersect at point E.

### Multiple Choice Options

- **A.** $27.70; 3.52
- **B.** $21.50; 10.16
- **C.** $22.16; 2.05
- **D.** $25.09; 4.846
