**Understanding Cost Concepts in Economics**

This image provides a multiple-choice quiz format to identify various cost concepts in economics. Below, each question pertains to a specific cost calculation or concept:

1. **(a) ΔTC / ΔQ :** 
   - Options: 
     - Marginal cost
     - Average (total) cost
     - Average variable cost

2. **(b) The amount by which total cost increases when an additional unit is produced:**
   - This describes the concept of Marginal cost.

3. **(c) TC / Q :**
   - Options: 
     - Marginal cost
     - Average (total) cost
     - Average variable cost

4. **(d) The total cost divided by the quantity of output:**
   - This is the Average (total) cost.

5. **(e) The change in total cost divided by the change in output:**
   - This describes the concept of Marginal cost.

6. **(f) VC / Q :**
   - This is the Average variable cost.

7. **(g) The sum of all costs that change as output changes divided by the number of units produced:**
   - This corresponds to the Average variable cost.

**Explanation of Concepts:**

- **Marginal Cost:** This is the increase in total cost when one more unit is produced. It is calculated as the change in total cost (ΔTC) divided by the change in quantity (ΔQ).

- **Average (Total) Cost:** This is the total cost (TC) divided by the quantity of output (Q), representing the cost per unit of output.

- **Average Variable Cost:** This is the variable cost (VC) divided by the quantity of output (Q), representing variable cost per unit of output.

Understanding these concepts is crucial for analyzing production efficiency and making informed economic decisions.
