To match the question with the correct answer based on the provided context, here's the appropriate pairing:

1. Determine the fixed cost.
   g. $200
   (Fixed cost is typically the y-intercept of the total cost function, indicating the cost when no units are produced.)

2. Determine the dollars for break-even.
   e. $300
   (This refers to the revenue level where the company breaks even—i.e., when total cost equals total revenue.)

3. Estimate the marginal revenue.
   c. 7.5
   (Marginal revenue refers to the increase in revenue for each additional unit sold.)

4. Label function B.
   a. Total revenue function
   (Function B is the total revenue curve.)

5. Label function A.
   f. Total cost function
   (Function A represents the total cost curve.)

6. Estimate the marginal cost.
   d. 2.5
   (Marginal cost is the increase in cost for each additional unit produced.)

7. Determine the number of units to break-even.
   b. 40 units
   (This is the quantity where total cost equals total revenue, leading to no profit or loss.)

Tip:

In economics, the break-even point occurs when total revenue equals total costs, resulting in zero profit or loss, a crucial concept for determining a company's financial viability.
