Complete the following Table: 
Step 1: Understanding the Concept:
Marginal Cost (MC) is the addition to the Total Cost (TC) when one more unit of output is produced.
Total Cost can be found by summing up the Marginal Costs of all units produced, assuming Total Fixed Cost (TFC) is zero or identifying it as the sum of variable costs.
Step 2: Key Formula or Approach:
The formula relating TC and MC is:
\[ TC_n = \sum_{i=1}^{n} MC_i \]
Or, \( TC_n = TC_{n-1} + MC_n \).
Step 3: Detailed Explanation:
Calculating TC for each unit:
- For Unit 1: \( TC = MC_1 = 30 \).
- For Unit 2: \( TC = TC_1 + MC_2 = 30 + 25 = 55 \).
- For Unit 3: \( TC = TC_2 + MC_3 = 55 + 20 = 75 \).
- For Unit 4: \( TC = TC_3 + MC_4 = 75 + 10 = 85 \).
Step 4: Final Answer:
