Question
Assume that a firm in a perfectly competitive industry faces a prevailing market price of $75 and has the following total cost schedule: Quantity: 0, 20, 40, 60, 80, 100, 120, 130, 140 TC: 300, 700, 1000, 1900, 2900, 4400, 6900, 10000, 15000 TR: Profit/Loss: MC: MR:
Solution
It seems like you want to calculate the Total Revenue (TR), Profit/Loss, Marginal Cost (MC), and Marginal Revenue (MR) for the firm. Here's how you can do it:
-
Total Revenue (TR): This is calculated by multiplying the quantity of goods sold by the market price. For example, if the firm sells 20 units at a price of 75 = $1500. You can do this for all quantities to get the TR.
-
Profit/Loss: This is calculated by subtracting the total cost (TC) from the total revenue (TR). For example, if the TR is 700, the profit would be 700 = $800. If the TC is greater than the TR, the firm is making a loss.
-
Marginal Cost (MC): This is the cost of producing one more unit of a good. It can be calculated by finding the change in TC when the quantity changes by one unit. For example, if the TC for producing 20 units is 1000, the MC of producing one more unit would be (700) / (40 - 20) = $15.
-
Marginal Revenue (MR): In a perfectly competitive market, the MR is equal to the market price, which is $75 in this case.
Remember to calculate these values for all quantities to complete your table.
