​$16,200
The image depicts a graph illustrating the relationship between price/cost and quantity for a firm, with various economic curves such as Marginal Cost (MC), Average Total Cost (ATC), Average Variable Cost (AVC), and the Marginal Revenue (MR) represented.

### Description of Graph Components:

**Axes:**
- **X-axis (Horizontal):** Represents Quantity, ranging from 0 to approximately 1,800 units.
- **Y-axis (Vertical):** Represents Price and Cost, ranging from 0 to 20.

**Curves:**
- **MC (Marginal Cost):** A positively sloped, red-colored line demonstrating the increase in cost with each additional unit produced.
- **ATC (Average Total Cost):** An upward-sloping orange line that shows the average cost per unit. This curve tends to decrease initially but rises as quantity increases.
- **AVC (Average Variable Cost):** This curve is slightly below the ATC, indicating variable costs per unit, also following an upward trend after decreasing initially.
- **MR (Marginal Revenue):** A horizontal pink line at the price level of $14, signifying the revenue gained from selling one more unit.

**Important Points and Lines:**
- **Price Line:** A constant horizontal blue line drawn at $20 showing the firm's product price level.
- **Intersection Points:**
  - The MR cuts the MC curve at Quantity 1,100.
  - The MC curve intersects the AVC at Quantity 1,350.
  - The MC curve crosses ATC at Quantity 1,800.

**Observations:**
- For quantities below 1,100, the marginal cost is lower than both the price and marginal revenue, suggesting the production is profitable.
- At quantity 1,100, the profit-maximizing output is where MR = MC.
- Beyond quantities of 1,350, the costs begin to rise faster as indicated by MC climbing above AVC and ATC. 
- At 1,800 units, the MC continues to rise above both ATC and AVC, indicating higher per-unit costs which may affect profitability.

This graph is typically used in microeconomics to illustrate cost structures and assist in decision-making for optimal production and pricing strategies.
