question
Assume that the equilibrium price in a perfectly competitive industry is $4.25. If a firm in this industry produced and sold 10 units with an average total cost of $5.00, the result would be:
answer
D.a loss of $7.50
Assuming that the equilibrium price in a perfectly competitive industry is $4.25, if a firm in this industry produced and sold 10 units with an average total cost of $5.00, the result would be a loss of $ 7.50
Data given: p = $ 4.25; q = 10 units; ATC = $ 5.00
Since p = AR = $ 4.25, then TR = q x p = 10 x $ 4.25 = $ 42.50
Since ATC = $ 5.00, then TC = q x ATC = 10 x $ 4.25 = $ 50.00
Since Profits = TR - TC, then Profits = $ 42.50 - $ 50.00 = - $ 7.50 (a loss)
Assuming that the equilibrium price in a perfectly competitive industry is $4.25, if a firm in this industry produced and sold 10 units with an average total cost of $5.00, the result would be a loss of $ 7.50

Since ATC = $ 5.00, then TC = q x ATC = 10 x $ 4.25 = $ 50.00
Since Profits = TR - TC, then Profits = $ 42.50 - $ 50.00 = - $ 7.50 (a loss)
