Consider a perfectly competitive market for wheat in Denver. There are 80 firms in the industry, each of which has the cost curves shown on the following graph:
#### Graph Description:
The graph illustrates the cost curves for a typical firm in the wheat industry with the following components:
- **Axes**:
- The horizontal axis represents the **Output** measured in thousands of bushels, ranging from 0 to 50.
- The vertical axis represents **Cost** measured in cents per bushel, ranging from 0 to 100.
- **Curves**:
- **AVC (Average Variable Cost) Curve**: Depicted in purple, this curve initially decreases, reaching a minimum, and then increases as output rises, forming a U-shape.
- **ATC (Average Total Cost) Curve**: Shown in green, the ATC curve lies above the AVC curve and follows a similar U-shape pattern.
- **MC (Marginal Cost) Curve**: Represented in orange, the MC curve initially decreases, reaches a minimum point, and then sharply increases as the output expands. The MC curve intersects the ATC and AVC curves at their minimum points.
This graph illustrates important economic principles, such as cost minimization and optimal production levels within the context of a perfectly competitive market.
![The image presents a graph illustrating the demand curve within a market. The y-axis represents the price in cents per bushel, ranging from 0 to 100 cents. The x-axis indicates the quantity in thousands of bushels, spanning from 0 to 4000.
**Graph Details:**
- **Demand Curve:** A downward-sloping line from a higher price and lower quantity (top-left) to a lower price and higher quantity (bottom-right).
- **Legend:** On the right side, there are symbols for "Supply Curve" (orange line) and "Equilibrium" (cross symbol), though they are not depicted on the graph.
**Text at the Bottom:**
- "At the current short-run market price, firms will [dropdown] in the short run. In the long run, [dropdown] the market given the current market price."
This represents a typical demand graph used in economics to demonstrate how price and quantity demanded are inversely related.](https://content.bartleby.com/qna-images/question/37e2f913-30b2-4c8c-98d5-339163057ff1/0fe14654-5d97-4f93-8826-b6890826564b/55j6pxh_processed.jpeg)

Assume that when the price is exactly equal to the average variable cost, the firm is indiſferent between producing zero shirts and the profit-maximizing quantity. Also, indicate whether the firm will produce, shut down, or be indifferent between the two in the short run. Lastly, determine whether it will make a profit, suffer a loss, or break even at each price. Price Quantity (Shirts) (Dollars per shirt) Produce or Shut Down?
