To calculate the marginal cost of increasing production from 3,000 to 5,000 units, we need to know the total cost of producing 3,000 units and the total cost of producing 5,000 units. The marginal cost (MC) is calculated using the formula:
\[ \text{MC} = \frac{\text{Change in Total Cost}}{\text{Change in Quantity}} \]
If you have the total costs for 3,000 and 5,000 units, you can apply those values to the formula. Since the information required to compute the marginal cost is not provided in your question, I can't compute it for you.
Please provide the total costs for 3,000 and 5,000 units, and I will help you calculate the marginal cost.
