![5. Assume the following total cost function.
\[
\begin{array}{|c|c|}
\hline
\text{Output} & \text{Total Cost} \\
\hline
0 & 50 \\
1 & 65 \\
2 & 85 \\
3 & 110 \\
4 & 140 \\
\hline
\end{array}
\]
What are the average total cost, average variable cost, average fixed cost, and marginal cost of producing 4 units of output?
**Explanation:**
To analyze the cost function, we identify the components:
- **Total Fixed Cost (TFC):** This is the cost when output is zero. In this case, \( TFC = 50 \).
- **Total Variable Cost (TVC):** This is calculated by subtracting the TFC from the TC at each level of output.
- **Total Cost (TC):** Given in the table for each output level.
To compute the various costs for 4 units:
1. **Average Total Cost (ATC):**
\[
ATC = \frac{TC}{\text{Output}} = \frac{140}{4} = 35
\]
2. **Average Variable Cost (AVC):**
\[
TVC = TC - TFC = 140 - 50 = 90
\]
\[
AVC = \frac{TVC}{\text{Output}} = \frac{90}{4} = 22.5
\]
3. **Average Fixed Cost (AFC):**
\[
AFC = \frac{TFC}{\text{Output}} = \frac{50}{4} = 12.5
\]
4. **Marginal Cost (MC):** The cost of producing one more unit of output.
\[
MC = TC_n - TC_{n-1} = 140 - 110 = 30
\]
These calculations help understand the cost dynamics at different production levels, essential for decision-making in resource allocation and pricing strategy.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F66e7cc61-872e-41d4-b674-d55ad2b38eb6%2F048217cb-7eb0-4807-93e7-55ac0239ff6e%2Fk1i02z5_processed.png&w=3840&q=75)
