To address the questions, we need to calculate the necessary cost metrics and determine the firm's optimal output and profitability under given conditions.

a. Complete the table

Let's calculate the costs for each unit produced:

  1. Marginal Cost (MC):

    • 1st unit: \$8
    • 2nd unit: \$6 (decreases by \$2)
    • 3rd unit: \$4 (decreases by \$2)
    • 4th unit: \$6 (increases by \$2)
    • 5th unit: \$8 (increases by \$2)
    • 6th unit: \$10 (increases by \$2)
  2. Total Variable Cost (TVC): Sum of marginal costs up to that unit.

    • 1st unit: \$8
    • 2nd unit: \$8 + \$6 = \$14
    • 3rd unit: \$14 + \$4 = \$18
    • 4th unit: \$18 + \$6 = \$24
    • 5th unit: \$24 + \$8 = \$32
    • 6th unit: \$32 + \$10 = \$42
  3. Total Cost (TC): Total Variable Cost + Total Fixed Cost (\$3).

    • 1st unit: \$8 + \$3 = \$11
    • 2nd unit: \$14 + \$3 = \$17
    • 3rd unit: \$18 + \$3 = \$21
    • 4th unit: \$24 + \$3 = \$27
    • 5th unit: \$32 + \$3 = \$35
    • 6th unit: \$42 + \$3 = \$45
  4. Average Variable Cost (AVC): Total Variable Cost / Quantity.

    • 1st unit: \$8 / 1 = \$8.00
    • 2nd unit: \$14 / 2 = \$7.00
    • 3rd unit: \$18 / 3 = \$6.00
    • 4th unit: \$24 / 4 = \$6.00
    • 5th unit: \$32 / 5 = \$6.40
    • 6th unit: \$42 / 6 = \$7.00
  5. Average Total Cost (ATC): Total Cost / Quantity.

    • 1st unit: \$11 / 1 = \$11.00
    • 2nd unit: \$17 / 2 = \$8.50
    • 3rd unit: \$21 / 3 = \$7.00
    • 4th unit: \$27 / 4 = \$6.75
    • 5th unit: \$35 / 5 = \$7.00
    • 6th unit: \$45 / 6 = \$7.50
b. What is the shutdown price?

The shutdown price is the minimum average variable cost. From the calculations above, the minimum AVC is \$6.00.

Shutdown price: \$6.00

c. If the market price is \$10, what is the firm's profit-maximizing output? What is the firm's total profit or loss?

To find the profit-maximizing output, we compare the market price to the marginal cost. The firm will produce up to the point where the price equals marginal cost, as long as the price is above AVC.

  • At 1st unit: MC = \$8, Price = \$10
  • At 2nd unit: MC = \$6, Price = \$10
  • At 3rd unit: MC = \$4, Price = \$10
  • At 4th unit: MC = \$6, Price = \$10
  • At 5th unit: MC = \$8, Price = \$10
  • At 6th unit: MC = \$10, Price = \$10

The firm will produce up to the 6th unit because the price equals the marginal cost at this point.

Output: 6 units

Total Profit or Loss:

Total Revenue (TR) = Price × Quantity = \$10 × 6 = \$60

Total Cost (TC) for 6 units = \$45

Profit = Total Revenue - Total Cost = \$60 - \$45 = \$15

Total: Profit: \$15

In summary, the firm should produce 6 units to maximize profit, resulting in a total profit of \$15.
